Neonatal thyrotoxicosis is most commonly due to transplacental transfer of maternal thyroid-stimulating hormone receptor antibodies (TRAb). Bioassay of thyrotropin receptor antibodies may help to determine the risk for neonatal hyperthyroidism. Thyrotoxicosis developed in a premature infant born to a mother with Graves' disease, with a low level of TRAb by bioassay. The infant was treated with carbimazole for two months, until TRAb had disappeared. Bioassay TRAb is not always reliable for predicting the development of neonatal hyperthyroidism in infants born to mothers with Graves' disease. Thyroid function should be measured in all these neonates.

Although important new strategies have improved outcomes for very preterm infants, males have greater mortality/morbidity than females. We investigated whether the excess of adverse later effects in males operated through poorer neonatal profile or if there was an intrinsic male effect. Male sex was significantly associated with higher birth weight, death or oxygen dependency (72% vs. 61%, boys vs. girls), hospital stay (97 vs. 86 days), pulmonary hemorrhage (15% vs. 10%), postnatal steroids (37% vs. 21%), and major cranial ultrasound abnormality (20% vs. 12%). Differences remained significant after adjusting for birth weight and gestation. At follow-up, disability, cognitive delay, and use of inhalers remained significant after further adjustment. We conclude that in very preterm infants, male sex is an important risk factor for poor neonatal outcome and poor neurological and respiratory outcome at follow-up. The increased risks at follow-up are not explained by neonatal factors and lend support to the concept of male vulnerability following preterm birth. Data came from the United Kingdom Oscillation Study, with 797 infants (428 boys) born at 23-28 wk gestational age. Thirteen maternal factors, 8 infant factors, 11 acute outcomes, and neurological and respiratory outcomes at follow-up were analyzed. Follow-up outcomes were adjusted for birth and neonatal factors sequentially to explore mechanisms for differences by sex.

Kinship, understood as biogenetic proximity, between a chosen animal model and a human patient counterpart, is considered essential to the process of ‘translating’ research from the experimental animal laboratory to the human clinic. In the Danish research centre, NEOMUNE, premature piglets are fed...... a novel milk diet (bovine colostrum) to model the effects of this new diet in premature infants. Our ethnographic fieldwork in an experimental pig laboratory and a neonatal intensive care unit (NICU) in 2013–2014 shows that regardless of biogenetics, daily practices of feeding, housing, and clinical care...... the researchers refer to as the ‘translatability’ of the results. In the NICU, parents of premature infants likewise imagine a kind of interspecies kinship when presented with the option to supplement mother's own milk with bovine colostrum for the first weeks after birth. However, in this setting the NICU...

Prematurely born infants are at high risk of respiratory morbidity following neonatal unit discharge, though prediction of outcomes is challenging. We have tested the hypothesis that cluster analysis would identify discrete groups of prematurely born infants with differing respiratory outcomes during infancy. A total of 168 infants (median (IQR) gestational age 33 (31-34) weeks) were recruited in the neonatal period from consecutive births in a tertiary neonatal unit. The baseline characteristics of the infants were used to classify them into hierarchical agglomerative clusters. Rates of viral lower respiratory tract infections (LRTIs) were recorded for 151 infants in the first year after birth. Infants could be classified according to birth weight and duration of neonatal invasive mechanical ventilation (MV) into three clusters. Cluster one (MV ≤5 days) had few LRTIs. Clusters two and three (both MV ≥6 days, but BW ≥or <882 g respectively), had significantly higher LRTI rates. Cluster two had a higher proportion of infants experiencing respiratory syncytial virus LRTIs (P = 0.01) and cluster three a higher proportion of rhinovirus LRTIs (P < 0.001) CONCLUSIONS: Readily available clinical data allowed classification of prematurely born infants into one of three distinct groups with differing subsequent respiratory morbidity in infancy. © 2018 Wiley Periodicals, Inc.

As younger preterm infants are able to survive, more extremely preterm infants are at risk of developing retinopathy of prematurity (ROP). To investigate the incidence, progression and risk factors of ROP in extremely preterm infants in Korea, the medical records of infants born before 25 weeks gestation were retrospectively reviewed. The criteria for laser treatment agreed with type 1 ROP as defined by the Early Treatment for Retinopathy of Prematurity study. Of the 121 infants included in the analysis, 119 (98.4%) infants developed any stage ROP, including 78 infants (64.5%) with type 1 ROP. The mean postmenstrual age (PMA) at the onset of any ROP and type 1 ROP were 33.5 and 36.1 weeks, respectively. All but one infant developed type 1 ROP after 31 weeks PMA. Univariate analysis showed that duration of total parenteral nutrition and onset of any ROP (PMA) were associated with the development of type 1 ROP. In conclusion, this study shows high incidence of ROP in extremely preterm infants and suggests that, although current screening protocols are feasible for most preterm infants born before 25 weeks gestation, earlier screening before 31 weeks PMA may be necessary in infants with an unstable clinical course.
Full Text Available Introduction: Preterm delivery is the delivery before 37 weeks of gestation are completed. The incidence of preterm birth ranges from 5 to 15%. Aims of the study were to determine the average body weight, Apgar score after one and five minutes, and the frequency of the most common complications in preterminfants.Methods: The study involved a total of 631 newborns, of whom 331 were born prematurely Aims of this study were to (24th-37th gestational weeks-experimental group, while 300 infants were born in time (37-42 weeks of gestation-control group.Results: Average body weight of prematurely born infants was 2382 grams, while the average Apgar score in this group after the fi rst minute was 7.32 and 7.79 after the fifth minute. The incidence of respiratory distress syndrome was 50%, intracranial hemorrhage, 28.1% and 4.8% of sepsis. Respiratory distresssyndrome was more common in infants born before 32 weeks of gestation. Mortality of premature infants is present in 9.1% and is higher than that of infants born at term.Conclusions: Birth body weight and Apgar scores was lower in preterm infants. Respiratory distress syndrome is the most common fetal complication of prematurity. Intracranial hemorrhage is the second most common complication of prematurity. Mortality of premature infants is higher than the mortality of infants born at term birth.

The use of noninvasive ventilation is a constantly evolving treatment option for respiratory disease in the premature infant. The goals of these noninvasive ventilation techniques are to improve gas exchange in the premature infant's lungs and to minimize the need for intubation and invasive mechanical ventilation. The goals of this article are to consider various uses of nasal interfaces, discuss skin care and developmental positioning concerns faced by the bedside nurse, and discuss the medical management aimed to reduce morbidity and mortality. This article explores the nursing role, the advances in medical strategies for noninvasive ventilation, and the team approach to noninvasive ventilation use in this population. Search strategy included a literature review on medical databases, such as EBSCOhost, CINAHL, PubMed, and NeoReviews. Innovative products, nursing research on developmental positioning and skin care, and advanced medical management have led to better and safer outcomes for premature infants requiring noninvasive ventilation. The medical focus of avoiding long-term mechanical ventilation would not be possible without the technology to provide noninvasive ventilation to these premature infants and the watchful eye of the nurse in terms of careful positioning, preventing skin breakdown and facial scarring, and a proper seal to maximize ventilation accuracy. This article encourages nursing-based research to quantify some of the knowledge about skin care and positioning as well as research into most appropriate uses for noninvasive ventilation devices.

Full Text Available BACKGROUND Preterm premature rupture of membrane is defined as rupture of foetal membrane before onset of labour at less than 37 completed weeks of gestation. Incidence of PPROM is around 3-10% of all deliveries. Primary complication for mother is infection and for foetus and neonate is prematurity, foetal distress, cord compression, deformation, pulmonary hypoplasia, necrotising enterocolitis and neurologic disorders. Most likely outcome is preterm delivery within 1 week. The aim of the study is to study the foetomaternal and neonatal outcome in PPROM patients and the common prevalent organism in PPROM. MATERIALS AND METHODS This is a cohort study of pregnant women from 24-37 weeks with PPROM admitted to IMCH for a period of 1 year, January 2016 to December 2016. 100 patients with PPROM were taken up for the study. The data was collected using the following inclusion and exclusion criteria. Inclusion criteria are gestational age 24-37 weeks confirmed by dates, clinical examination and ultrasound with lack of uterine contractions for at least 1 hour from PPROM; single live pregnancy in vertex presentation; PPROM confirmed by direct visualisation, neonates admitted in NICU soon after delivery. RESULTS 49% of patients with preterm premature rupture of membranes were from 18-24 years.68% of patients had a latency period of 3 weeks.15% of patients had maternal tachycardia, 4% had tenderness of uterus and 4% had leucocytosis and 14% had an elevated CRP. Thus, clinical chorioamnionitis was seen in 14% of patients, 38% of babies born had prematurity and 2% had sepsis and 19% had respiratory distress syndrome and hyperbilirubinaemia, 2% had perinatal asphyxia, 2% had anomalies, 1% had necrotising enterocolitis and 5% were NND. Common organisms were normal flora, E. coli, Streptococci and Enterococci. CONCLUSION PPROM increases the incidence of maternal morbidity with longer hospital stay due to chorioamnionitis. Neonatal morbidity is increased due to

The aims of this study were to: examine the expression of open bite in prematurely born children and discuss the etiological factors that may lead to bite it. The subjects were 328 prematurely born (cross-sectional study of the Collaborative Perinatal Project in the 1960s and 1970s. Dental documents, including casts and photographs, were taken once at the age of 6-12 years in the mixed dentition. The occlusion was recorded by examining and measuring the hard stone casts. Vertical open bite was recorded only for full erupted teeth. The statistical method used was chi-square analysis. Significant differences in the incidence of anterior open bite (from left to right canine) was found between the preterm and control groups and between gender and ethnic groups. The prevalence of anterior open bite was nearly 9% in the preterm group and almost 7% in the control group. African Americans (9%) had a significantly greater incidence of open bite than Caucasians (3%; Pbite than boys (8% vs 6%; Pbite was increased--especially in preterm African American boys compared to controls (11% vs 8%). The results show differences in the development of anterior open bite between ethnic and gender groups. Premature birth may also influence dental occlusal development. Of importance are the patient's: general health condition; respiratory infections; inadequate nasal- and mouth-breathing; oral habits; and other medical problems. Preterm children may be relatively more predisposed to etiological factors for the development of anterior open bite.

Full Text Available Early prediction of bronchopulmonary dysplasia (BPD may facilitate tailored management for neonates at risk. We investigated whether easily accessible flow data from a mechanical ventilator can predict BPD in neonates born extremely premature (EP. In a prospective population-based study of EP-born neonates, flow data were obtained from the ventilator during the first 48 h of life. Data were logged for >10 min and then converted to flow–volume loops using custom-made software. Tidal breathing parameters were calculated and averaged from ≥200 breath cycles, and data were compared between those who later developed moderate/severe and no/mild BPD. Of 33 neonates, 18 developed moderate/severe and 15 no/mild BPD. The groups did not differ in gestational age, surfactant treatment or ventilator settings. The infants who developed moderate/severe BPD had evidence of less airflow obstruction, significantly so for tidal expiratory flow at 50% of tidal expiratory volume (TEF50 expressed as a ratio of peak tidal expiratory flow (PTEF (p=0.007. A compound model estimated by multiple logistic regression incorporating TEF50/PTEF, birthweight z-score and sex predicted moderate/severe BPD with good accuracy (area under the curve 0.893, 95% CI 0.735–0.973. This study suggests that flow data obtained from ventilators during the first hours of life may predict later BPD in premature neonates. Future and larger studies are needed to validate these findings and to determine their clinical usefulness.

Full Text Available Premature rupture of membranes (PROM is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. With respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following PROM and the role of the duration of rupture of membranes in producing morbidities and mortalities in these neonates in our hospital. Among 2357 pregnant women, we found 163 (6.91% cases of premature rupture of the fetal membranes in Tehran Vali-e-Asr Hospital during April 2001 to April 2002. Route of delivery was cesarean section in 65.6% of women. Urinary tract infection occured in 1.8%, maternal leukocytosis and fever in 20.2% and 5.5%, chorioamnionitis in 6.1%, fetal tachycardia in 1.2% and olygohydramnios in 4.9%. Gestational age in 138 (86% of neonates was less than 37 completed weeks. Thirty five infants (21.47% had respiratory distress syndrome and 33 (20.245% had clinical sepsis. Pneumonia in 6 (3.7% and skeletal deformity in 7 (4.294% were seen. Rupture of membrane of more than 24 hours duration occurred in 71 (43.6% of the patients. Comparison of morbidities between two groups of neonates and their mothers according to the duration of PROM (less and more than 24 hours showed significant differences in NICU admission, olygohydramnios, maternal fever, leukocytosis and chorioamnionitis rates (p24 hr of PROM with an odds ratio of 2.68 and 2.73, respectively. Positive blood and eye cultures were detected in 16 cases during 72 hours of age. Staphylococcus species, klebsiella, E.coli and streptococcus were the predominant organisms among positive blood cultures. Mortality was seen in 18 (11% of neonates because of respiratory failure, disseminated intravascular coagulation, septic shock, and a single case of congenital toxoplasmosis. In this study, the prevalence of prematurity, sepsis and prolonged rupture of membrane

Contemporary clinical practice for the care of the prematurely born babies has markedly improved their rates of survival so that most of these babies are expected to grow up to live a healthy functional life. Since the clinical follow up is of short duration (years), only limited data are available to relate non-communicable diseases in adult life to events and interventions in the neonatal period. The major events that could have a programming effect include (1) Intrauterine growth restriction (2) Interruption of pregnancy with change in redox and reactive oxygen species injury (3) Nutritional and pharmacological protocols for Clinical care (4) Nutritional care in the first two years resulting in accelerated weight gain. The available data are discussed in the context of perturbations in one carbon (methyl transfer) metabolism and its possible programming effects. Although direct evidence for genomic methylation is not available, clinical and experimental data on impact of redox and ROS, of low protein intake, excess methionine load and vitamin A, on methyl transfers are reviewed. The consequences of antenatal and postnatal administration of glucocorticoids are presented. Analysis of the correlates of insulin sensitivity at older age, suggests that premature birth is the major contributor, and is compounded by gain in weight during infancy. We speculate that premature interruption of pregnancy and neonatal interventions by effecting one carbon metabolism may cause programming effects on the immature baby. These can be additive to the effects of intrauterine environment (growth restriction) and are compounded by accelerated growth in early infancy. PMID:25054678

Conclusion: Chorioamnionitis not only causes premature deliveries, but is also associated with neonatal complications and increased mortality. Clinical findings and infectious markers in mother or infant do not predict the diagnosis of histological chorioamnionitis. Therefore, placental histopathology may have a role in predicting neonatal outcome in premature deliveries, especially those below 30 weeks.

Full Text Available Study aim: Premature birth is one of the major problems of obstetrics, leading to numerous complications that are associated with prematurity, for instance balance disorders. The aim of the study was to assess the impact of premature birth on the ability to maintain balance in children commencing their school education. Material and methods: The study included children aged 6-7 years. The study group consisted of 59 children (31 girls and 28 boys, mean age 6.38 ± SD 0.73 born prematurely between 24 and 35 weeks of gestation. The control group consisted of 61 children (28 girls and 33 boys, mean age 6.42 ± 0.58 born at term. The research utilized standardized test tools - one-leg open-eyed and closed-eyed standing test, one-leg jumping test - and an original questionnaire survey. Results: The children born at term achieved better results in the majority of tests. The comparison of girls and boys born prematurely and at term showed no statistically significant difference between them in terms of dynamic balance, static balance or total balance control. The comparison of the tests performed on the right and left lower limb in prematurely born children showed no statistically significant differences. Conclusion: Premature birth affects the ability to maintain body balance. The results of the study indicate the need to develop coordination skills that shape body balance in prematurely born children.

Persistent patency of the ductus arteriosus is a major cause of morbidity and mortality in premature infants. In infants born prior to 28 weeks of gestation, a hemodynamically-significant patent ductus arteriosus (PDA) can cause cardiovascular instability, exacerbate respiratory distress syndrome, prolong the need for assisted ventilation, and increase the risk of bronchopulmonary dysplasia, intraventricular hemorrhage, renal dysfunction, intraventricular hemorrhage, cerebral palsy, and mortality. In this article, we review the pathophysiology, clinical features, and assessment of hemodynamic significance, and provide a rigorous appraisal of the quality of evidence to support current medical and surgical management of PDA of prematurity. Cyclo-oxygenase inhibitors such as indomethacin and ibuprofen remain the mainstay of medical therapy for PDA, and can be used both for prophylaxis as well as rescue therapy to achieve PDA closure. Surgical ligation is also effective and is used in infants who do not respond to medical management. Although both medical and surgical treatment have proven efficacy in closing the ductus, both modalities are associated with significant adverse effects. Because the ductus does undergo spontaneous closure in some premature infants, improved and early identification of infants most likely to develop a symptomatic PDA could help in directing treatment to the at-risk infants and allow others to receive expectant management.

Preterm birth can impact on child development. As seen previously, children born preterm present more behavioral and/or emotional problems than do full-term counterparts. In addition to gestational age, neonatal clinical status should be examined to better understand the differential impact of premature birth on later developmental outcomes. The aim of the present study was to systematically review empirical studies on the relationship between prematurity, neonatal health status, and behavioral and/or emotional problems in children. A systematic search of the PubMed, PsycINFO, Web of Science, and LILACS databases for articles published from 2009 to 2014 was performed. The inclusion criteria were empirical studies that evaluated behavioral and/or emotional problems that are related to clinical neonatal variables in children born preterm. Twenty-seven studies were reviewed. Results showed that the degree of prematurity and birth weight were associated with emotional and/or behavioral problems in children at different ages. Prematurity that was associated with neonatal clinical conditions (e.g., sepsis, bronchopulmonary dysplasia, and hemorrhage) and such treatments as corticoids and steroids increased the risk for these problems. The volume and abnormalities of specific brain structures also were associated with these outcomes. In conclusion, the neonatal health problems associated with prematurity present a negative impact on later child emotional and adapted behavior. © 2016 Michigan Association for Infant Mental Health.

Evaluation of the extracerebral space on CT resulted as follows: The existence of the etracerebral space in the parieto-occipital region (PO-ECS) was physiological findings characteristic to premature infants. Its incidence was higher and the width of the space was greater, in those of premature infants. Generally PO-ECS disappeared around 40 weeks of gestation, while it tended to remaine beyond 40 weeks in premature infants born after less than 30 weeks of pregnancy. The appearance and disappearance of the PO-ECS may present some approach to learning the development of the brain in premature infants. (Ueda, J.)

Retinopathy of prematurity is a leading cause of childhood blindness around the world. The Department of Ophthalmology at the Semmelweis University and the Peter Cerny Neonatal Emergency and Ambulance Service started an innovative Premature Eye Rescue Program to reduce the non-essential transport of premature babies suffering from retinopathy of prematurity. During the first 5 years 186 eyes of 93 premature babies were treated at the bedside with stage 3 retinopathy of prematurity in the primary hospitals. In this first 5-years period the authors reduced the number of transports of premature babies for laser treatment; 93 children avoided the unnecessary transport, saving altogether a distance of 21,930 kilometers for children, as well as the ambulance service. The Premature Eye Rescue Program offers a good and effective alternative for treatment of retinopathy in the primary hospitals. The authors propose the national extension of this program.
Full Text Available Intraventricular hemorrhage (IVH is an important cause of brain injury in premature neonates. Current study tries to define associated risk factors of IVH in preterm neonates in Aliasghar Children Hospital during 2008 to 2011. In this study, the risk factors have been evaluated in premature neonates with IVH, who had at least one brain sonography since their admission in NICU. A total of 63 premature neonates with IVH were assessed. Mean gestational age was 29.81 (24-34 weeks and mean birth weight was 1290.83±382.96 gr. Other risk factors such as sex, mode of delivery, history of using infertility drugs, maternal disease, maternal hypertension and preeclampsia, lumbar puncture, ventilator therapy and pneumothorax were considered. Because no absolute treatment for IVH is available, identifying risk factors is important in prevention and management of IVH.

To evaluate mandibular function, signs, and symptoms of temporomandibular disorders (TMDs) and headache in prematurely born 8- to 10-year-old children, and to compare the findings with matched full-term born controls. Seventy-three preterm children were selected from the Medical Birth Register--one group comprising 36 extremely preterm children born before the 29th gestational week, the other group 37 very preterm children born during gestational weeks 29 to 32. The preterm children were compared with a control group of 41 full-term children matched for gender, age, nationality, and living area. The subjective symptoms of TMD and headache were registered using a questionnaire. Mandibular function, signs, and symptoms of TMD and headache were registered. TMD diagnoses were set per Research Diagnostic Criteria for temporomandibular disorders (RDC/TMD). No significant differences between groups or gender were found for TMD diagnoses according to RDC/TMD or for headache. The preterm children had smaller mandibular movement capacity than the full-term control group, but when adjusting for weight, height, and head circumference mostly all group differences disappeared. Prematurely born children of 8 to 10 years of age did not differ from full-term born children when considering diagnoses according to RDC/TMD, signs, and symptoms of TMD or headache.

Maternal obesity is associated with increased systemic inflammation and an increased risk of preterm premature rupture of membranes. There is an established association between an inflammatory intrauterine environment and adverse neonatal outcomes that is independent of gestational age and mediated by the fetal inflammatory response. It is unknown whether the maternal systemic inflammation that is present in obese women influences the intrauterine environment and predisposes the fetus to adverse neonatal outcomes after preterm premature rupture of membranes. The purpose of this study was to determine whether maternal obesity is associated with adverse neonatal outcomes in pregnancies that are complicated by preterm premature rupture of membranes. This was a secondary analysis of the Maternal-Fetal Medicine Units Network Randomized Clinical Trial on the Beneficial Effects of Antenatal Magnesium Sulfate. Women with singleton pregnancies that were affected by preterm premature rupture of membranes who delivered live-born infants between 24 + 0 and 33 + 6 weeks of gestation were included. An adverse neonatal outcome was defined as a composite outcome of neonatal death, severe necrotizing enterocolitis, respiratory distress syndrome, sepsis, or severe intraventricular hemorrhage. The rates of the composite outcome were compared between obese (body mass index, ≥30 kg/m(2)) and nonobese women. Multivariable logistic regression was used to evaluate the independent effect of obesity on neonatal outcomes. Magnesium sulfate administration, steroid administration, maternal diabetes mellitus, gestational age at delivery, indomethacin exposure, birthweight, and chorioamnionitis were all considered as possible covariates in the multivariable regression models. Three hundred twenty-five of the 1288 women (25.2%) who were included were obese, and 202 of these women (62.2%) had neonates with adverse outcomes. In univariable analysis, maternal prepregnancy obesity was associated
To determine the frequency of early onset neonatal sepsis in newborn with various duration of preterm premature rupture of membranes (PPROM). Study Design: Cross sectional study. Place and Duration of Study: Neonatal Intensive Care Unit Combined Military Hospital, Lahore from November 2009 to November 2010. Material and Methods: Neonates of singleton pregnancies complicated by preterm premature rupture of the membranes (PPROM) with delivery between 30 and 36 weeks gestation were included in the study. The overall frequency of neonatal sepsis was calculated on clinical and serological basis. Comparison of the frequency of sepsis among groups with varying duration of rupture of membranes was done. Results: Out of 164 babies, 84 (51.2%) were female and 80 (48.8%) were male. Mean maternal age was 23 years (range: 18-36 years). Mean gestational age was 33 weeks (range: 30-36 weeks). Sepsis was suspected in 41(25%) babies on clinical grounds. C-reactive protein was raised in 36 (22%) neonates. There was statistically insignificant difference between clinical versus serological diagnosis (p=0.515). Frequency of neonatal sepsis was significantly higher in mothers with longer duration of rupture of membrane (p < 0.001). Conclusion: Frequency of neonatal sepsis was observed to be 22%. PPROM is an important risk factor for early onset neonatal sepsis. (author)

Context: Prematurely born children have a high risk of developmental and behavioral disabilities. Cerebral abnormalities at term age have been clearly linked with later behavior alterations, but existing studies did not focus on the amygdala. Moreover, studies of early amygdala development after premature birth in humans are scarce. Objective: To compare amygdala volumes in very preterm infants at term equivalent age (TEA) and term born infants, and to relate premature infants’ amygdala volumes with their performance on the Laboratory Temperament Assessment Battery (Lab-TAB) fear episode at 12 months. Participants: Eighty one infants born between 2008 and 2014 at the University Hospitals of Geneva and Lausanne, taking part in longitudinal and functional imaging studies, who had undergone a magnetic resonance imaging (MRI) scan at TEA enabling manual amygdala delineation. Outcomes: Amygdala volumes assessed by manual segmentation of MRI scans; volumes of cortical and subcortical gray matter, white matter and cerebrospinal fluid (CSF) automatically segmented in 66 infants; scores for the Lab-TAB fear episode for 42 premature infants at 12 months. Results: Amygdala volumes were smaller in preterm infants at TEA than term infants (mean difference 138.03 mm3, p amygdala volumes were larger than left amygdala volumes (mean difference 36.88 mm3, p Amygdala volumes showed significant correlation with the intensity of the escape response to a fearsome toy (rs = 0.38, p = 0.013), and were larger in infants showing an escape response compared to the infants showing no escape response (mean difference 120.97 mm3, p = 0.005). Amygdala volumes were not significantly correlated with the intensity of facial fear, distress vocalizations, bodily fear and positive motor activity in the fear episode. Conclusion: Our results indicate that premature birth is associated with a reduction in amygdala volumes and white matter volumes at TEA, suggesting that altered amygdala development

This study aimed at analyzing the family participation in the premature assistance in a university hospital neonatal ICU. Data were collected from the participant observation. Results showed that despite of the mother's presence in the daily life of their premature children placed in a hospital, family isn't inserted in the work process and mothers are the only ones who take part of the cares. This participation basically happens in the execution of maternity care, especially at the medium risk unity, the mother and premature family are less welcomed and there isn't any partnership between the care team and the family, there aren't team interventions in order to turn premature family in autonomous subject to promote health and life quality to baby's life.

Significant advances in perinatal and neonatal medicine over the last 20 years and the recent emergence of fetal surgery has resulted in anesthesia providers caring for a growing number of infants born at the margin of viability. Anesthetic management in this patient population has to take into consideration the immature function of many vital organ systems as well as the effects of the underlying disease processes, which can frequently lead to severe physiological derangements. Accordingly, premature infants presenting for major surgeries early in life can represent a significant anesthetic challenge. However, even with advanced anesthetic and surgical management and optimal intensive care, extremely premature infants face substantial postoperative morbidity and mortality, as well as prolonged hospital courses. In this article, we will discuss the following questions: How far have we come in improving outcomes of extreme prematurity? And what will the future medical and societal challenges be, as we continue to redefine the limits of viability? © 2011 Blackwell Publishing Ltd.

To investigate the relationship between placenta and perinatal outcomes, in preterm infants born to mothers with preterm premature rupture of fetal membrane (PPROM). We report detailed histology of placentas and perinatal outcomes of infants from 79 PPROM pregnancies. Placental histologic pattern and adverse perinatal outcomes were assessed by logistic regression, adjusting for gestational age at birth, birth weight and interval from rupture of membrane to delivery. Mean gestational age at membrane rupture was 29.5 ± 3.4 weeks. The incidence of histologic chorioamnionitis (HCA), fetal inflammatory response (FIR) and vascular thrombotic abnormalities in placental histologic examination were 63.3, 25.3 and 78.5%, respectively. Neonates with FIR showed significantly higher incidence of periventricular leukomalacia (PVL) (85% versus 59.3%, p = 0.0364) at brain ultrasonography, than neonates without FIR, in univariate analysis, but not in logistic regression analysis. In logistic regression analysis, the odds ratio of low Apgar score at 1 min in the neonates with clinical chorioamnionitis was 5.009 (95% CI, 1.242-20.195). The odds ratio of neonatal seizure in the neonates with FIR and vascular thrombotic problem was 7.486 (95% CI, 1.617-34.653). Our findings support the association between FIR with vascular thrombotic problem in placenta and neonatal seizure, in pregnancies with PPROM.
Full Text Available holoprosencephaly is a rare congenital brain malformation resulting from failure of diverticulation and cleavage of primitive prosencephalon which occurs at 4 - 8th week of gestation and is usually associated with multiple midline facial anomalies. it is the most common forebrain developmental anomaly in humans with prevalence of 1/16,000 in live borns, an incidence as high as 1:250 in conceptuses, and a worldwide distribution6. The etiology of HPE is very heterogeneous. First, this pathology can be caused by environmental or metabolic factors. The only formally recognized environmental factors are insulin-dependent diabetes mellitus (1% risk of HPE and maternal alcoholism with a risk that cumulates with smoking . Clinical expression is variable, extending in unbroken sequence from a small brain with a single cerebral ventricle and cyclopia to clinically unaffected carriers in familial holoprosencephaly. Here. we report a boy 39 weeks neonatal case of holoprosencephaly with Antenatal ultrasonographic diagnosis, with microcephaly, hypotelorism, flat nose, a single nostril, a midline cleft lip and palate microcephaly.

To determine if glycerin suppositories were effective in reducing total duration of phototherapy in premature neonates. We hypothesized that glycerin suppositories would have no effect on phototherapy duration or total serum bilirubin levels. Prospective randomized controlled double-blinded trial. Level IV NICU. Neonates born between 30 weeks, 0 days and 34 weeks, 6 days gestational age who developed physiologic hyperbilirubinemia needing phototherapy. Neonates were randomized to the no-suppository group or to the suppository group. Neonates were randomized to receive glycerin suppositories every 8 hours while under phototherapy or to a sham group. The primary outcome was total hours of phototherapy. Secondary outcomes included peak total serum bilirubin levels, time from start to discontinuation of phototherapy, rate of decline in bilirubin levels, repeat episodes of phototherapy, and number of stools while the neonates received phototherapy. A total of 39 neonates were assigned to the no-suppository group and 40 to the suppository group. Withholding suppositories was not inferior to providing suppositories. The total hours of phototherapy were not longer (i.e., noninferior) among neonates not provided suppositories (61 ± 53 hours) than among those given suppositories (72 ± 49 hours). There were no differences in peak bilirubin levels, rate of bilirubin decline, or repeat episodes of phototherapy. Routine use of glycerin suppositories among preterm neonates who receive phototherapy does not affect bilirubin levels or phototherapy duration.

Full Text Available Placental histologic examination can assist in revealing the mechanism leading to preterm birth. Accumulating evidence suggests an association between intrauterine pathological processes, morbidity and mortality of premature infants, and their long term outcome. Neonatal brain activity is increasingly monitored in neonatal intensive care units by amplitude integrated EEG (aEEG and indices of background activity and sleep cycling patterns were correlated with long term outcome. We hypothesized an association between types of placental lesions and abnormal neonatal aEEG patterns.To determine the association between the placental lesions observed in extreme preterm deliveries, and their neonatal aEEG patterns and survival.This prospective cohort study included extreme premature infants, who were born ≤ 28 weeks of gestation, their placentas were available for histologic examination, and had a continues aEEG, soon after birthn = 34. Infants and maternal clinical data were collected. aEEG data was assessed for percentage of depressed daily activity in the first 3 days of life and for sleep cycling. Associations of placental histology with clinical findings and aEEG activity were explored using parametric and non-parametric statistics.Twenty two out of the 34 newborns survived to discharge. Preterm prelabor rupture of membranes (PPROM or chorioamnionitis were associated with placental lesions consistent with fetal amniotic fluid infection (AFI or maternal under perfusion (MUP (P < 0.05. Lesions consistent with fetal response to AFI were associated with absence of SWC pattern during the 1st day of life. Fetal-vascular-thrombo-occlusive lesions of inflammatory type were negatively associated with depressed cerebral activity during the 1st day of life, and with aEEG cycling during the 2nd day of life (P<0.05. Placental lesions associated with MUP were associated with depressed neonatal cerebral activity during the first 3 days of life (P = 0

A cohort of extremely prematurely born children and matched term controls was assessed at 5 years of age. The parents completed a questionnaire on their behavioral and social development. The purpose was to illuminate whether the children's general intellectual ability and parental sensitivity were...... associated with behavioral and social development. The index children exhibited more hyperactive behavior and had poorer social skills than the controls. Lower Full Scale IQ (FSIQ) was associated with outward reacting and hyperactive behavior and poorer social skills. Sensitive parenting was associated...... with less outward reacting and less hyperactive behavior. When controlling for differences in FSIQ and parental sensitivity, the index children persisted to have an increased risk of exhibiting hyperactive behavior but not poorer social skills. The index children with normal intellectual development...

Despite substantial progress in neonatal care over the past two decades leading to improved survival of extremely premature infants, extreme prematurity continues to be associated with long term neurodevelopmental impairments. Cerebral white matter injury is the predominant form of insult in preterm brain leading to adverse neurological consequences. Such brain injury pattern and unfavorable neurologic sequelae is commonly encountered in premature infants exposed to systemic inflammatory states such as clinical or culture proven sepsis with or without evidence of meningitis, prolonged mechanical ventilation, bronchopulmonary dysplasia, necrotizing enterocolitis and chorioamnionitis. Underlying mechanisms may include cytokine mediated processes without direct entry of pathogens into the brain, developmental differences in immune response and complex neurovascular barrier system that play a critical role in regulating the cerebral response to various systemic inflammatory insults in premature infants. Understanding of these pathologic mechanisms and clinical correlates of such injury based on serum biomarkers or brain imaging findings on magnetic resonance imaging will pave way for future research and translational therapeutic opportunities for the developing brain.

Kinship, understood as biogenetic proximity, between a chosen animal model and a human patient counterpart, is considered essential to the process of 'translating' research from the experimental animal laboratory to the human clinic. In the Danish research centre, NEOMUNE, premature piglets are fed a novel milk diet (bovine colostrum) to model the effects of this new diet in premature infants. Our ethnographic fieldwork in an experimental pig laboratory and a neonatal intensive care unit (NICU) in 2013-2014 shows that regardless of biogenetics, daily practices of feeding, housing, and clinical care hold the potential for stimulating and eroding kinship relations between human and nonhuman actors. In the laboratory, piglets and researchers form 'interspecies-milk-kinships' that entail the intimate care crucial to keeping the compromised piglets alive during the experiments, thereby enhancing what the researchers refer to as the 'translatability' of the results. In the NICU, parents of premature infants likewise imagine a kind of interspecies kinship when presented with the option to supplement mother's own milk with bovine colostrum for the first weeks after birth. However, in this setting the NICU parents may perceive the animality of bovine colostrum, and the background information obtained in piglets, as a threat to the infants' connection to their biological parents as well as the larger human collective. Our study argues that the 'species flexibility' of premature beings profoundly shapes the translational processes in the field of neonatology research. Copyright © 2017 Elsevier Ltd.

Adults born preterm are at risk of developing cardiovascular morbidities. The aim of this study was to evaluate the relationship between retinopathy of prematurity (ROP) and blood pressure (BP) and salivary cortisol levels during adulthood. Sixty-nine subjects (mean age 22.6 years) were included. Subjects were adults who were: (a) ex-preterm infants with severe ROP (n = 22), born at gestational age (GA) <30 weeks with a birth weight (BW) <1,000 g, (b) ex-preterm infants with no/mild ROP (n = 21), born at GA <28 weeks with a BW <1,000 g, or (c) full-term controls (n = 26). Anthropometric data, office BP, ambulatory BP, and morning and evening salivary cortisol were analyzed. As adults, ex-preterm infants with severe ROP had on average 7.4 mm Hg higher systolic office BP than those with no/mild ROP (p = 0.019) and controls (p = 0.007). A high cortisol level, tall height, and severe ROP were independent predictors of higher ambulatory systolic BP during adulthood in forward stepwise regression analysis, independent of GA. Our results indicate that preterm infants with severe abnormal retinal vascular development during the neonatal period may be at an increased risk for increased BP during adulthood. We found no differences between those with no/mild ROP as infants and controls with regard to BP data. © 2017 The Author(s) Published by S. Karger AG, Basel.

Preterm (PT) birth results in long-term alterations in functional and structural connectivity, but the related changes in anatomical covariance are just beginning to be explored. To test the hypothesis that PT birth alters patterns of anatomical covariance, we investigated brain volumes of 25 PTs and 22 terms at young adulthood using magnetic resonance imaging. Using regional volumetrics, seed-based analyses, and whole brain graphs, we show that PT birth is associated with reduced volume in bilateral temporal and inferior frontal lobes, left caudate, left fusiform, and posterior cingulate for prematurely born subjects at young adulthood. Seed-based analyses demonstrate altered patterns of anatomical covariance for PTs compared with terms. PTs exhibit reduced covariance with R Brodmann area (BA) 47, Broca's area, and L BA 21, Wernicke's area, and white matter volume in the left prefrontal lobe, but increased covariance with R BA 47 and left cerebellum. Graph theory analyses demonstrate that measures of network complexity are significantly less robust in PTs compared with term controls. Volumes in regions showing group differences are significantly correlated with phonological awareness, the fundamental basis for reading acquisition, for the PTs. These data suggest both long-lasting and clinically significant alterations in the covariance in the PTs at young adulthood. © The Author 2015. Published by Oxford University Press.

This longitudinal, descriptive study described the level of depressive symptoms in mothers of preterm infants from birth through 27 months corrected age and examined factors associated with depressive symptoms. The framework for the study was guided by an ecological developmental systems perspective and an adaptation of the Preterm Parental Distress Model. In this model, we hypothesize that a mother's emotional distress to the birth and parenting of a prematurely born child is influenced by personal and family factors, severity of the infant's health status, and illness-related stress and worry. Participants were 102 mothers of preterm infants who were off the ventilator and not otherwise dependent on major technology at enrollment. Mean depressive symptoms scores on the Center for Epidemiologic Studies Depression Scale (CES-D) during hospitalization were high and more than half the mothers (63%) had scores of > or =16 indicating risk of depression. Depressive scores declined over time until 6 months and then were fairly stable. Unmarried mothers, mothers of infants who were rehospitalized, and mothers who reported more maternal role alteration stress during hospitalization and worry about the child's health had more depressive symptoms through the first year. Mothers who reported more parental role alteration stress during hospitalization (odds ratio [OR] = 1.570, 95% confidence interval [CI]: 1.171-2.104) and more worry about the child's health (OR = 2.350, 95% CI: 1.842-2.998) were more likely to experience elevated CES-D scores that put them at risk of depression. Also, mothers of rehospitalized infants had decreasing odds of elevated CES-D scores over time (OR = 0.982 per week, 95% CI: 0.968-0.996). Findings have implications for the support of mothers during hospitalization and in the early years of parenting a preterm infant.

Prematurity is a public health problem that calls to focus on its causes and consequences through a trans disciplinary approach. There are no studies analyzing premature birth from the perspective of individuals born preterm. To identify social representations associated with premature birth of individuals born preterm in the 1990s in Argentina. Twelve focus groups were conducted with individuals born preterm with a birth weightparents' memories and experiences, overprotection body, education, relationship with the medical practice and knowledge. The methodology used allowed to create a space for mutual recognition and reflection for participants. Prematurity is a significant element, especially in those who suffered major sequelae. Adolescents and youth give a warning on the negative effects caused by overprotective parents and reveal the possibility of redefining the challenges associated with their history of premature birth.

To evaluate neonatal survival after prolonged preterm premature rupture of membranes (PROM) in the era of antenatal corticosteroids, surfactant, and inhaled nitric oxide. A single-center retrospective cohort study of neonates born from 2002-2011 after prolonged (1 week or more) preterm (less than 24 weeks of gestation) rupture of membranes was performed. The primary outcome was survival to discharge. Neonates whose membranes ruptured less than 24 hours before delivery (n=116) were matched (2:1) on gestational age at birth, sex, and antenatal corticosteroid exposure with neonates whose membranes ruptured 1 week or more before delivery (n=58). Analysis used conditional logistic regression for categorical data and Wilcoxon signed rank test for continuous data. The prolonged preterm PROM exposed and unexposed cohorts had survival rates of 90% and 95%, respectively, although underpowered to assess the statistical significance (P=.313). Exposed neonates were more likely have pulmonary hypoplasia (26/58 exposed, 1/114 unexposed, Prupture (20.4 weeks exposed, 22.3 weeks unexposed, P=.189), length of rupture (3.7 weeks exposed, 6.4 weeks unexposed, P=.717), and lowest maximal vertical pocket before 24 weeks of gestation (0 cm exposed, 1.4 cm unexposed, P=.114) did not discriminate between survivors and nonsurvivors after exposure to prolonged preterm PROM. With antenatal steroid exposure and aggressive pulmonary management, survival to discharge after prolonged preterm PROM was 90%. Pulmonary morbidities were common. Of note, the data were limited to women who remained pregnant 1 week or longer after rupture of membranes.

Evaluation of maternal, obstetrics e neonatal features in both spontaneous preterm births (PTB) with or without preterm premature rupture of membranes (PPROM). Retrospective study of single fetus pregnancies with PTB between 2003 and 2012. PTB associated with ou without PPROM. Exclusion criterias: PTB by medical indication due to fetal/maternal disease and all non accessible or incomplete clinical files. Different characteristics were compared between two groups of PTB: spontaneous PTB without PPROM (sPTB) versusPPROM. Kolmogorov-Smirnov, Levene, χ2, t Student and Mann-Withney tests were used for statistical analysis. From 2,393 PTB of single fetus, 1,432 files were analysed, from which 596 were sPTB and 836 PPROM. The socioeconomic conditions were similar in both groups. Multiparity (50.7 versus 40.3%), personal history of previous PTB (20.8 versus10.2%), cervical length (18.2 versus27.2 mm), lower body index mass (23.4 versus 24.3 kg/m2) and higher infectious parameters (Protein C Reactive: 2.2 versus1.2 mg/L; Leukocytes: 13.3 versus 12.4 x109) were more frequent in PBTs (p<0,001). Neonatal outcomes, specially neurologic outcomes (4.7 versus2.8%, p<0,001), were worst in PBTs. PTB with or without PPROM has a complex etiology. From all evaluated features in our study, only maternal thinness, multiparity with a previous PTB, the cervical length and worst systemic infections parameters were significant in sPTB. This group also showed worst neonatal outcomes, specially on neurological outcomes.

Full Text Available Extremely preterm infants are at high risk of neonatal mortality and adverse outcome. Survival rates are slowly improving, but increased survival may come at the expense of more handicaps.Prospective population-based cohort study of all infants born at 23 to 27 weeks of gestation in The Netherlands in 2007. 276 of 345 (80% infants were born alive. Early neonatal death occurred in 96 (34.8% live born infants, including 61 cases of delivery room death. 29 (10.5% infants died during the late neonatal period. Survival rates for live born infants at 23, 24, 25 and 26 weeks of gestation were 0%, 6.7%, 57.9% and 71% respectively. 43.1% of 144 surviving infants developed severe neonatal morbidity (retinopathy of prematurity grade ≥3, bronchopulmonary dysplasia and/or severe brain injury. At two years of age 70.6% of the children had no disability, 17.6% was mild disabled and 11.8% had a moderate-to-severe disability. Severe brain injury (p = 0.028, retinopathy of prematurity grade ≥3 (p = 0.024, low gestational age (p = 0.019 and non-Dutch nationality of the mother (p = 0.004 increased the risk of disability.52% of extremely preterm infants born in The Netherlands in 2007 survived. Surviving infants had less severe neonatal morbidity compared to previous studies. At two years of age less than 30% of the infants were disabled. Disability was associated with gestational age and neonatal morbidity.

Neonates born to opioid-maintained mothers are at risk of developing neonatal abstinence syndrome (NAS), which often requires pharmacological treatment. This study examined the effect of opioid maintenance treatment on the incidence and timing of NAS, and compared two different NAS treatments (phenobarbital versus morphine hydrochloride). Fifty-three neonates born to opioid-maintained mothers were included in this study. The mothers received methadone (n=22), slow-release oral morphine (n=17) or buprenorphine (n=14) throughout pregnancy. Irrespective of maintenance treatment, all neonates showed APGAR scores comparable to infants of non-opioid dependent mothers. No difference was found between the three maintenance groups regarding neonatal weight, length or head circumference. Sixty percent (n=32) of neonates required treatment for NAS [68% in the methadone-maintained group (n=15), 82% in the morphine-maintained group (n=14), and 21% in the buprenorphine-maintained group (n=3)]. The mean duration from birth to requirement of NAS treatment was 33 h for the morphine-maintained group, 34 h for the buprenorphine-maintained group and 58 h for the methadone-maintained group. In neonates requiring NAS treatment, those receiving morphine required a significantly shorter mean duration of treatment (9.9 days) versus those treated with phenobarbital (17.7 days). Results suggest that morphine hydrochloride is preferable for neonates suffering NAS due to opioid withdrawal.

One goal of the study was to identify "new" statistically independent risk factors for treatment-demanding retinopathy of prematurity (ROP). Another goal was to evaluate whether any new risk factors could explain the increase in the incidence of treatment-demanding ROP over time in Denmark. A retrospective, register-based cohort study. The study included premature infants (n = 6490) born in Denmark from 1997 to 2008. The study sample and the 31 candidate risk factors were identified in 3 national registers. Data were linked through a unique civil registration number. Each of the 31 candidate risk factors were evaluated in univariate analyses, while adjusted for known risk factors (i.e., gestational age [GA] at delivery, small for gestational age [SGA], multiple births, and male sex). Significant outcomes were analyzed thereafter in a backward selection multiple logistic regression model. Treatment-demanding ROP and its associations to candidate risk factors. Mechanical ventilation (odds ratio [OR], 2.84; 95% confidence interval [CI], 1.99-4.08; P large study population, blood transfusion and mechanical ventilation were the only new statistically independent risk factors to predict the development of treatment-demanding ROP. Modification in the neonatal treatment with mechanical ventilation or blood transfusion did not cause the observed increase in the incidence of preterm infants with treatment-demanding ROP during a recent birth period (2003-2008).

This study demonstrates that infants who are born prematurely and who have experienced at least 40days of intensive or special care have increased brain neuronal responses to noxious stimuli compared to healthy newborns at the same postmenstrual age. We have measured evoked potentials generated by noxious clinically-essential heel lances in infants born at term (8 infants; born 37-40weeks) and in infants born prematurely (7 infants; born 24-32weeks) who had reached the same postmenstrual age (mean age at time of heel lance 39.2+/-1.2weeks). These noxious-evoked potentials are clearly distinguishable from shorter latency potentials evoked by non-noxious tactile sensory stimulation. While the shorter latency touch potentials are not dependent on the age of the infant at birth, the noxious-evoked potentials are significantly larger in prematurely-born infants. This enhancement is not associated with specific brain lesions but reflects a functional change in pain processing in the brain that is likely to underlie previously reported changes in pain sensitivity in older ex-preterm children. Our ability to quantify and measure experience-dependent changes in infant cortical pain processing will allow us to develop a more rational approach to pain management in neonatal intensive care.

Full Text Available We examined the effects of prematurity (37 weeks of gestation and low birthweight (2500 g on mental health outcomes among US children aged 2–17 years. The 2011-2012 National Survey of Children’s Health ( = 95,677 was used to estimate prevalence of parent-reported mental health problems in children. Prevalence of mental disorders was 22.9% among children born prematurely, 28.7% among very-low-birth-weight (1500 g children, and 18.9% among moderately low-birth-weight (1500–2499 g children, compared with 15.5% in the general child population. Compared to those born full term, children born prematurely had 61% higher adjusted odds of serious emotional/behavioral problems, 33% higher odds of depression, and 58% higher odds of anxiety. Children born prematurely had 2.3 times higher odds of autism/ASD, 2.9 times higher odds of development delay, and 2.7 times higher odds of intellectual disability than term children. Very-low-birth-weight children had 3.2 times higher odds of autism/ASD, 1.7 times higher odds of ADD/ADHD, 5.4 times higher odds of development delay, and 4.4 times higher odds of intellectual disability than normal-birth-weight children. Social factors were significant predictors of mental disorders in both premature/low-birth-weight and term/normal-birth-weight children. Neurodevelopmental conditions accounted for the relationship between prematurity and depression/anxiety/conduct problems. Prematurity and low birthweight are significant risk factors for mental health problems among children.
Full Text Available Preterm birth represents a high risk of neurodevelopmental disabilities when associated with white-matter damage. Recent studies have reported cognitive deficits in children born preterm without brain injury on MRI at term-equivalent age. Understanding the microstructural and metabolic underpinnings of these deficits is essential for their early detection. Here, we used diffusion-weighted imaging and single-voxel 1H magnetic resonance spectroscopy (MRS to compare brain maturation at term-equivalent age in premature neonates with no evidence of white matter injury on conventional MRI except diffuse excessive high-signal intensity, and normal term neonates. Thirty-two infants, 16 term neonates (mean post-conceptional age at scan: 39.8±1 weeks and 16 premature neonates (mean gestational age at birth: 29.1±2 weeks, mean post-conceptional age at scan: 39.2±1 weeks were investigated. The MRI/MRS protocol performed at 1.5T involved diffusion-weighted MRI and localized 1H-MRS with the Point RESolved Spectroscopy (PRESS sequence. Preterm neonates showed significantly higher ADC values in the temporal white matter (P<0.05, the occipital white matter (P<0.005 and the thalamus (P<0.05. The proton spectrum of the centrum semiovale was characterized by significantly lower taurine/H2O and macromolecules/H2O ratios (P<0.05 at a TE of 30 ms, and reduced (creatine+phosphocreatine/H2O and (glutamine+glutamate/H2O ratios (P<0.05 at a TE of 135 ms in the preterm neonates than in full-term neonates. Our findings indicate that premature neonates with normal conventional MRI present a delay in brain maturation affecting the white matter and the thalamus. Their brain metabolic profile is characterized by lower levels of creatine, glutamine plus glutamate, and macromolecules in the centrum semiovale, a finding suggesting altered energy metabolism and protein synthesis.

Bleeding due to acquired coagulation disorders is a common complication in premature neonates. In this clinical setting, standard coagulation laboratory tests might be unsuitable to investigate the hemostatic function as they reflect the concentration of pro-coagulant proteins but not of anti-coagulant proteins. Thromboelastography (TEG), providing a more complete assessment of hemostasis, may be able to overcome some of these limitations. Unfortunately, experience on the use of TEG in premature neonates is very limited and, in particular in this population, reference ranges of TEG parameters have not been yet evaluated. To evaluate TEG in preterm neonates, and to assess their reference ranges. One hundred and eighteen preterm neonates were analyzed for TEG in a retrospective cohort study. Double-sided 95% reference intervals were calculated using a bootstrap method after Box-Cox transformation. TEG parameters were compared between early-preterm and moderate-/late-preterm neonates and between bleeding and non-bleeding preterm neonates. Comparing early-preterm with moderate-/late-preterm neonates, TEG parameters were not statistically different, except for fibrinolysis which was significantly higher in early preterm neonates. Platelet count significantly correlated with α angle and MA parameters. Bleeding and non-bleeding neonates had similar TEG values. These results reinforce the concept that in stable preterm neonates, in spite of lower concentration of pro- and anti-coagulants proteins, the hemostasis is normally balanced and well functioning.

Preeclampsia may result in uteroplacental insufficiency and chronic intrauterine fetal distress. The aim of this study is to address this issue investigating neuronal apoptosis in an experimental model of preeclampsia and to evaluate the neurological outcome of the perinatal asphyxia in the neonates born to preeclamptic mother. Two out of four pregnant Sprague-Dawley rats (preeclamptic group) were given water containing 1.8% NaCl on gestation day 15 and 22 in order to establish the model of preeclampsia whereas other two (non-preeclamptic group) received normal diet. A model of perinatal asphyxia was established on the postnatal 7th day to one preeclamptic and one non-preeclamptic dam. Overall 23 pups born to overall four dams were decapitated to assess neuronal apoptosis by the TUNEL assay. The number of apoptotic neuronal cells was significantly higher in the preeclampsia groups in comparison with the control group (p = 0.006 and p = 0.006, respectively). It was also significantly higher in the asphyctic/non-preeclamptic group than the count in the control group (p = 0.01). There was also significant difference between both asphyctic groups (p = 0.003). We conclude that preeclampsia causes small babies for the gestational age and cerebral hypoplasia. Both preeclampsia and perinatal asphyxia can cause increased neuronal apoptosis in the neonatal brains. However, the prognosis for neurological outcome is much worse when the perinatal asphyxia occurs in newborns born to preeclamptic mothers.

We tested the hypothesis that the carotid bodies would be smaller in individuals born prematurely or exposed to perinatal oxygen therapy when compared individuals born full term that did not receive oxygen therapy. A retrospective chart review was conducted on patients who underwent head/neck computed tomography angiography (CTA) at the Mayo Clinic between 10 and 40 years of age (n = 2503). Patients were identified as premature ( body images captured during the CTA were performed. Carotid body visualization was possible in 43% of patients and 52% of age, sex, and body mass index (BMI)-matched controls but only 17% of juvenile preterm subjects (p = 0.07). Of the carotid bodies that could be visualized, widest axial measurements of the carotid bodies in individuals born prematurely (n = 7, 34 ± 4 weeks gestation, birth weight: 2460 ± 454 g; average size: 2.5 ± 0.2 cm) or individuals exposed to perinatal oxygen therapy (n = 3, 38 ± 2 weeks gestation, Average size: 2.2 ± 0.1 cm) were not different when compared to controls (2.3 ± 0.2 cm and 2.3 ± 0.2 cm, respectively, p > 0.05). Carotid body size, as measured using CTA, is not smaller in adults born prematurely or exposed to perinatal oxygen therapy when compared to sex, age, and BMI-matched controls. However, carotid body visualization was lower in juvenile premature patients. The decreased ability to visualize the carotid bodies in these individuals may be a result of their prematurity.

This study aimed to determine whether there are differences in the incidence of metabolic bone disease (MBD) between preterm neonates first exposed to diuretics prior to 2 weeks of life versus those exposed after 2 weeks. This study was a retrospective analysis of premature neonates born at a tertiary care center between 2011 and 2015 who received either furosemide or chlorothiazide. The primary outcome was incidence of MBD. Secondary outcomes included growth, electrolyte disturbances, oxygen requirement, and length of stay. A total of 147 patients were included. Early initiation (n = 90) and late initiation (n = 57) arms were balanced with respect to birth weight and gestational age. There was no difference in incidence of MBD in the early group (76%) versus the late group (65%; p = 0.164). Stratification by cumulative dose showed incidence of 85% in patients receiving ≥8 mg/kg of furosemide, compared with 68% and 64% of those in the <4 mg/kg and 4 to 7.9 mg/kg strata, respectively (p = 0.06). The early group experienced greater reductions in length-for-age growth during diuretic therapy (-70% versus -40%; p = 0.009). Electrolyte abnormalities were more prevalent in the early group. Although there was no difference in duration of mechanical ventilation, duration of supplemental oxygen requirement was reduced in the late group (75 versus 89 days; p = 0.003). Timing of diuretic initiation did not affect incidence of MBD. Increased cumulative furosemide exposure may be associated with higher incidence. Patients first exposed to diuretics within 2 weeks of life are at higher risk for electrolyte abnormalities and reduced growth velocity.

Preterm premature rupture of membranes (PPROM) complicates 1% of all pregnancies and occurs in one third of all preterm deliveries. Midtrimester PPROM is often followed by spontaneous miscarriage and elective termination of ongoing pregnancies is offered in many countries. The aim of this retrospective descriptive cohort study was to investigate the natural history of midtrimester PPROM in a jurisdiction where termination of pregnancy in the absence of maternal compromise is unavailable. Cases of midtrimester PPROM diagnosed between 14 and 23 + 6 weeks' gestation during April 2007 to June 2012 were identified following a manual search of all birth registers, pregnancy loss registers, annual reports, ultrasound reports, emergency room registers and neonatal death certificates at Cork University Maternity Hospital - a large (circa 8500 births per annum) tertiary referral maternity hospital in southwest Ireland. Cases where delivery occurred within 24 h of PPROM were excluded. The prevalence of midtrimester PPROM was 0.1% (42 cases/44,667 births). The mean gestation at PPROM was 18 weeks. The mean gestation at delivery was 20 + 5 weeks, with an average latency period of 13 days. Ten infants were born alive (23%; 10/42). The remainder (77%; 32/42) died in utero or intrapartum. Nine infants were resuscitated. Two infants survived to discharge. The overall mortality rate was 95% (40/42). Five women had clinical chorioamnionitis (12%; 5/42) but 69% demonstrated histological chorioamnionitis. One woman developed sepsis (2.4%; 1/42). Other maternal complications included requirement of intravenous antibiotic treatment (38%; 17/42), retained placenta (21%, 9/42) and post-partum haemorrhage (12%; 5/42). This study provides useful and contemporary data on midtrimester PPROM. Whilst fetal and neonatal mortality is high, long-term survival is not impossible. The increased risk of maternal morbidity necessitates close surveillance.
Full Text Available Background: Birth of a premature neonate is associated with hospital admission and separation from the family. Admission of the neonates intervenes on infant-mother attachment and so adversely affects on the quality of care given by the mother, and subsequently increases the risk of delayed behavioral problems in the children. Aim: To assess the effectiveness of mother empowerment program on the premature infant-mother attachment. Methods: In this randomized clinical trial, 70 mothers of premature infants, admitted to the neonatal intensive care unit (NICU of Omolbanin hospital of Mashhad in 2014, were divided into of intervention and control groups. The Empowerment program was a multi-step treatment program, in which information about the premature infants was provided to mothers through an illustrated booklet with a workbook and audio file in each step. Mothers in the control group received information and routine care according to the hospital guideline. The mother-infant attachment was measured after the intervention using the maternal and neonatal behaviors Avant tool. Data analysis was performed using chi-square and t-student tests by SPSS software version 11.5. Results:The mean scores of maternal attachment behaviors after the intervention in the empowerment and control groups were (56.62±8.06 and (39.51±7.77, respectively; the difference between the groups was statistically significant (P

Full Text Available Objective: Understand the maternal experience with premature children in neonatal intensive care unit. Methods: This is a qualitative and descriptive study. A questionnaire was used with semi-structured interview type, analyzed by the technique of content analysis and discussed, using the theoretical framework. The sample consisted of 11 mothers who accompanied their babies every day in the Neonatal Intensive Care Unit. Results: After discourse analysis emerged the following categories: experiencing maternal feelings in relation to the baby at risk; the meaning of the neonatal unit for mothers of premature infants, maternal perceptions about prematurity and experiencing the formation of the maternal-filial bond. Conclusions:The mother of premature experiences difficult times in the face of risk and instability of the baby, causing ambivalent feelings in relation to prematurity. Nevertheless, it was found thatfeelings of happiness, love and desire to see your baby being discharged form hospital and live with his family, were significant in relation to feelings of sadness and fear of losing her child.

Our aim was to assess the utility of serum thyroxine and thyroid stimulating hormone performed at 10-14 days of life in diagnosing congenital hypothyroidism (CH) in babies born to mothers with hypothyroidism. This was a retrospective study of all babies born in a tertiary referral centre for neonatology over a 12-month period. Infants who had thyroid function testing (TFT) checked at 10-14 days of life because of maternal hypothyroidism during the period of study were included. The results of the newborn bloodspot and day 10-14 TFT were recorded along with whether or not patients were subsequently treated. Of the 319 patients included in the study, only two patients were found to have CH and in both cases the newborn blood spot had been abnormal. No extra cases of CH were detected from the thyroid test at 10-14 days and this practice should be discontinued due to the robust nature of existing newborn screening programmes. What is Known: • Congenital hypothyroidism(CH) is the commonest preventable cause of childhood intellectual impairment. • Family history of hypothyroidism has been implicated as a risk factor for CH. • CH has formed part of newborn screening since the 1970s. What is New: • There is no research recommending thyroid function testing at 10-14 days of life to detect CH in neonates born to mothers with hypothyroidism. • Thyroid function testing at 10-14 days of life does not improve diagnostic yield for CH in babies born to mothers with hypothyroidism. • Newborn blood spot remains the mainstay for accurate and timely diagnosis of CH.
Full Text Available Introduction: Family, especially mother, is faced with numerous challenges by experiencing a premature birth. Since knowing about mother‟s efforts regarding prematurely born infant helps us in our comprehensive understanding of the impact of this incident on the family system and its performance. The present study was carried out to explore the mothers' strategies regarding prematurely born infant. Methods: In a conventional qualitative content analysis, data was collected through purposive sampling by semi-structured deep interviews with 18 mothers who had prematurely born infant during 2012-2013 in the teaching hospitals of the north and northwest of Iran. All the interviews were recorded, typed, and finally analyzed. Results: Data analysis resulted in the extraction of categories of "asking for help, elevating capacity and reducing personal responsibilities and commitments". These categories were revealed in mothers respectively by the different sub-categories of "religious appeal and relying on beliefs, seeking information from the treatment and caring team, participating in infant‟s care, companionship and support of family and friends”, “focusing on positive thinking and imagination, patience and strength " and "ignoring some routine affairs and reducing role-related activities and duties". Conclusion: Considering the uniqueness of the mother's role in responding to the needs of infants, healthcare system should consider mothers as real target in the intervention strategies in order to promote health and quality of life, so maybe this way, the burden of care and management of critical situations caused by a premature birth on the mother can be reduced.
Full Text Available Prematurity and poor weight gaining are important causes for neonatal hospitalization. The present study aimed to investigate the role of medium-chain triglyceride (MCT oil via massage therapy as a supplementary nutritional method on the weight gain of Neonatal Intensive Care Units (NICU-hospitalized neonates. This randomized clinical trial performed among 121 stable premature neonates hospitalized in the NICU of Qaem Educational Hospital, Mashhad, Iran. They were randomly divided into three groups: oil-massage, massage alone and control groups. These groups were compared on the basis of weight gain during a one-week interval. The three groups were matched for sex, mean gestational age, birth weight, head circumference, delivery, and feeding type (P>0.05. The mean weight gain on the 7th day in the oil massage group was 105±1.3gr and 52±0.1gr in the massage group; whereas 54±1.3gr weight loss was observed in the control group. Significant differences were observed between the oil-massage group and the other two groups, respectively (P=0.002 and P=0.000. The findings of this study suggest that transcutaneous feeding with MCT oil massage therapy in premature neonates can result in accelerated weight gain in this age group with no risk of NEC.

The aim of this study was to identify adverse neonatal outcomes and identifies the predictors of adverse neonatal outcomes in premature rupture of membranes before 26 weeks. Data were collected between January 2005 and December 2011 from all pregnant women who presented preterm premature rupture of membranes (PPROM) between 18 and 26 complete weeks of gestation and were admitted to one of three Brazilian institutes. The adverse outcomes included mortality or the development of a severe morbidity during the length of stay in the neonatal intensive care unit (NICU). The descriptive statistics of the population were reported. A multiple logistic regression was performed for each predictor of neonatal adverse outcomes. The area under the receiver operating characteristics curves for the birth weight was calculated. Composite adverse outcomes during the NICU stay occurred in 82.1% (n = 23) of the cases and included 33 (54%) neonatal deaths, 19 (67.8%) cases of retinopathy of prematurity (ROP), 13 (46.4%) cases of pulmonary hypoplasia (BPD), 8 (28.5%) cases of periventricular-intraventricular hemorrhage (PIH) and 3 (10.7%) cases of periventricular leukomalacia (PVL). Only 17.8% (n = 5) of the neonates survived without morbidity. The area under the curve for the birth weight was 0.90 (95% IC: 0.81-0.98) for the prediction of mortality. PPROM before 26 weeks has a high morbidity and mortality, and the significant predictors of neonatal mortality and adverse outcomes were antibiotic prophylaxis, latency period, GA at birth and birth weight. Nevertheless, the only independent significant predictor of survival rate was birth weight.

Full Text Available Objective: to study the nanostructure of red blood cell membranes in premature babies with neonatal respiratory distress syndrome (NRDS, by applying atomic force microscopy. Subjects and methods. The investigation included 27 newborn infants, of them 13 premature babies with NRDS formed a study group. The mean gestational age was 33.1±2.3 weeks; their birth weight was 1800±299.3 g. A comparison group consisted of 14 full-term babies with favorable pregnancy and term labor. The mean gestational age of the babies was 39.4±0.5 weeks; their birth weight was 3131.7±588.8 g; the infants had a one minute Apgar score of 8±0.4. Their red blood cells were examined using an atomic force microscope. The objects to be examined were residual umbilical cord blood (RUCB from the premature infants; central venous blood after 7 hours of birth and neonatal venous blood taken on day 7 of life. Results. RUCB from full-term babies contained planocytes that were a major morphological type of red blood cells. In physiological pregnancy and acute fetal hypoxia, the morphological composition of red blood cells in premature neonates with NRDS was close to that in full-term babies. The planocytes are also a major morphological type of red blood cells in the premature infants; the frequency of their occurrence varies. Stomatocytes are typical of all the neonates in the NRDS group; their frequency levels vary greatly: from 8 to 65% of the total number of erythrocytes. The examination revealed that the premature infants of 31—36 weeks gestation were characterized by abnormal erythrocyte shapes that showed a high variability. At birth, the premature babies were found to have changes in the nanostructure of red blood cell membranes, which were influenced by intrauterine hypoxia. The first-order value reflecting flickering in the red blood cell membrane varies to the most extent. Conclusion. Atomic force microscopy showed that the greatest changes in the structure of red

X-ray radiography is a commonly used diagnostic method for premature neonates. However, because of higher radiosensitivity and young age, premature neonates are more sensitive to the detrimental effects of ionising radiation. Therefore, it is important to monitor and optimise radiation doses at the neonatal intensive care unit (NICU). The number of X-ray examinations, dose area product (DAP) and effective doses are evaluated for three Dutch NICUs using digital flat panel detectors. Thorax, thorax abdomen and abdomen protocols are included in this study. Median number of examinations is equal to 1 for all three hospitals. Median DAP ranges between 0.05 and 1.02 μGy m2 for different examination types and different weight categories. These examinations result in mean effective doses between 4 ± 4 and 30 ± 10 μSv per examination. Substantial differences in protocols and doses can be observed between hospitals. This emphasises the need for up-to-date reference levels formulated specifically for premature neonates. (authors)

To examine the accommodative amplitude and convergence in 10-year-old prematurely born children previously screened for retinopathy of prematurity (ROP) and to compare with full-term controls of the same age. Two-hundred and thirteen prematurely born and 217 children born at term were included. Accommodative amplitude and near-point convergence were assessed, together with best-corrected visual acuity (VA). A questionnaire was answered regarding possible problems at school. Binocular accommodation (P = 0.03) and convergence (P = 0.003) were significantly poorer in prematurely born children. Accommodation was correlated to neurological findings in the preterm group, but not to the degree of prematurity or stage of ROP. Regarding convergence there were no correlations to neurology, stage of ROP, or degree of prematurity. For neither accommodation nor convergence were any correlations with distance and near VA found. Preterm children had a higher prevalence of school problems, and there was an association with poor accommodation. Prematurely born children had poorer accommodation and convergence than full-term children, but no association with near VA was found. The reduction of accommodative amplitude and convergence was small and was probably of little clinical significance. However, it may have additional effects on other ophthalmological problems and school problems in the preterm group.

Objective: the present study was aimed at analyzing the value of the early diagnosis of hemodynamic changes in hemorrhages and hypoxic-ischemic events in premature, very-low-birth-weight neonates through the evaluation of images and resistance index measurement by means of transcranial Doppler ultrasonography. Materials and methods: fifty premature, very-low-birth-weight neonates were submitted to transcranial Doppler ultrasonography with sequential transfontanellar and transtemporal techniques. Results: cerebral abnormalities were detected in 32% of the neonates (22% with intracranial hemorrhage, 8% with periventricular leukomalacia, and 2% with toxoplasmosis). Among the 34 cases (68%) of neonates in whom no brain lesion was detected at transcranial Doppler ultrasonography, 18 (53%) presented changes in the resistance index. Such resistance index varied according to the time of the examination. Conclusion: there is a correlation between the presence of cerebral hemodynamic changes demonstrated by resistance index measurements and the subsequent development of hemorrhages and hypoxic-ischemic lesions. Although not being a death predictor, changes in the resistance index are associated with the severity of the clinical conditions in preterm, very-low-birth-weight neonates. (author)

Neonatal brain hemorrhage (NBH) of prematurity is an unfortunate consequence of preterm birth. Complications result in shunt dependence and long-term structural changes such as posthemorrhagic hydrocephalus, periventricular leukomalacia, gliosis, and neurological dysfunction. Several animal models are available to study this condition, and many basic mechanisms, etiological factors, and outcome consequences, are becoming understood. NBH is an important clinical condition, of which treatment may potentially circumvent shunt complication, and improve functional recovery (cerebral palsy, and cognitive impairments). This review highlights key pathophysiological findings of the neonatal vascular-neural network in the context of molecular mechanisms targeting the posthemorrhagic hydrocephalus affecting this vulnerable infant population.

Congenital cutaneous candidiasis is a very rare disease with less than 100 cases published in the medical literature. Neonates having this disease present with systemic skin lesions caused by intrauterine Candida infections. We present a case of threatened premature delivery due to Candida chorioamnionitis, which caused both maternal postpartum endometritis and neonatal congenital cutaneous candidiasis. A 34-year-old woman who was admitted for fetal membrane bulging at 20 weeks of gestation underwent McDonald cervical cerclage. We diagnosed threatened premature delivery due to intrauterine infection; therefore, we terminated the gestation by cesarean section at 24 weeks of gestation. Fungi-like yeast was detected in infantile gastric juice. Histopathological findings of the placenta revealed that Candida albicans mycelium invaded the placenta, chorioamniotic membrane and umbilical cord. © 2012 The Authors.

There are conflicting results regarding tocolysis in cases of preterm premature rupture of membranes. Delaying delivery may reduce neonatal morbidity because of prematurity and allow for prenatal corticosteroids and, if necessary, in utero transfer. However, that may increase the risks of maternofetal infection and its adverse consequences. The objective of the study was to investigate whether tocolytic therapy in cases of preterm premature rupture of membranes is associated with improved neonatal or obstetric outcomes. Etude Epidémiologique sur les Petits Ages Gestationnels 2 is a French national prospective, population-based cohort study of preterm births that occurred in 546 maternity units in 2011. Inclusion criteria in this analysis were women with preterm premature rupture of membranes at 24-32 weeks' gestation and singleton gestations. Outcomes were survival to discharge without severe morbidity, latency prolonged by ≥48 hours and histological chorioamnionitis. Uterine contractions at admission, individual and obstetric characteristics, and neonatal outcomes were compared by tocolytic treatment or not. Propensity scores and inverse probability of treatment weighting for each woman were used to minimize indication bias in estimating the association of tocolytic therapy with outcomes. The study population consisted of 803 women; 596 (73.4%) received tocolysis. Women with and without tocolysis did not differ in neonatal survival without severe morbidity (86.7% vs 83.9%, P = .39), latency prolonged by ≥48 hours (75.1% vs 77.4%, P = .59), or histological chorioamnionitis (50.0% vs 47.6%, P = .73). After applying propensity scores and assigning inverse probability of treatment weighting, tocolysis was not associated with improved survival without severe morbidity as compared with no tocolysis (odds ratio, 1.01 [95% confidence interval, 0.94-1.09], latency prolonged by ≥48 hours (1.03 [95% confidence interval, 0.95-1.11]), or histological chorioamnionitis

Full Text Available Objective: to reveal a relationship of placental inflammatory changes to bacterial infection in premature neonates with respiratory failure. Material and methods. Bronchoalveolar aspirate was bacteriologically studied in 157 premature neonates with respiratory distress syndrome (NRDS; the total and differential leukocyte counts were measured in their peripheral blood. The levels of the cytokines IL-1^3, IL-4, IL-6, and TNF-a were studied in different biological fluids of mothers and their babies; the placentas were also morphologically examined. Results. An analysis of bacterial cultures from the tracheobronchial tree revealed no growth of bacterial microflora in 61.8% of cases, Enterococcus faecalis and Staphylococcus epidermidis were isolated in 6.4 and 8.3% of the infants, respectively; Staphylococcus haemolyticus, Staphylococcus capitis, Enterobacter agglomerans, and hemolytic group A Streptococcus were seen in 1.9% each; moreover, 1.3% of the newborn infants were found to have Bacillus spp., Staphylococcus aureus, Escherichia coli, Acinetobacter spp., and Serratia marcescens. Other microorganisms and a microbial association were encountered in 8.9% of cases. Placental morphological examination revealed different inflammatory changes concurrent with chronic and acute placental insufficiency. The investigation demonstrated that the maternal peripheral plasma levels of IL-1^, IL-4, IL-6, and TNF-a were within the physiological range at the end of the first period of delivery. The amniotic fluid displayed elevated IL-6 and TNF-a concentrations and normal IL-4 and IL-1e levels, suggesting that there was an intrauterine inflammatory process. Conclusion. Premature birth is associated with various placental inflammatory changes, which causes intrauterine stimulation of macrophages in the chorionic villi. Specific immune defense mechanisms that prevent the development of a fetal infectious process, i.e. the maternal infectious process, may induce

Does vitrification of Day 3 and Day 5 embryos adversely affect birth outcomes of singletons and twins in comparison with peers born after fresh embryo transfer? Neonatal health parameters, including the prevalence of congenital malformations, in singletons and twins born after embryo vitrification are similar to or slightly better than after fresh embryo transfer. Although vitrification, rather than slow-freezing, of embryos is routine practice nowadays, convincing evidence regarding the safety for the offspring is sparse. Literature data comprise results from mostly small-sized studies or studies including only Day 3 or only Day 5 vitrified embryo transfers. Overall, better or comparable perinatal outcomes, in terms of higher birthweight and lower risk for small-for-gestational age or for low birthweight, have been reported for singletons born after vitrified embryo transfer compared with fresh embryo transfer. According to the single available study with sufficient sample size, the congenital malformation rate was found to be comparable after vitrified and fresh embryo transfers. Data were collected from 960 cycles after transfer of embryos vitrified on Day 3 (n = 457) or Day 5 (n = 503) and from 1644 cycles after fresh embryo transfer on Day 3 (n = 853) or Day 5 (n = 791), performed between 2008 and 2013 at the Centre for Reproductive Medicine of the university hospital UZ Brussel. Outcome measures were neonatal health in terms of birthweight, small-for-gestational age, prematurity rate, perinatal death and major/minor/total malformation rate. Perinatal health parameters of 11 stillborns and 1061 live borns (827 singletons and 234 twins) in the vitrified group and of 28 stillborns and 1838 live borns (1374 singletons and 464 twins) in the fresh embryo group are reported. Within 3 months after birth, children in the two study groups were assessed clinically with special attention to congenital malformations by a paediatrician blinded to the type of embryo

Caffeine is effective in the treatment of apnea of prematurity. Although caffeine therapy has a benefit on gross motor skills in school-aged children, effects on neurobehavioral outcomes are not fully understood. We aimed to investigate effects of neonatal caffeine therapy in very low birth weight (500-1250 g) infants on neurobehavioral outcomes in 11-year-old participants of the Caffeine for Apnea of Prematurity trial. Thirteen academic hospitals in Canada, Australia, Great Britain, and Sweden participated in this part of the 11-year follow-up of the double-blind, randomized, placebo-controlled trial. Measures of general intelligence, attention, executive function, visuomotor integration and perception, and behavior were obtained in up to 870 children. The effects of caffeine therapy were assessed by using regression models. Neurobehavioral outcomes were generally similar for both the caffeine and placebo group. The caffeine group performed better than the placebo group in fine motor coordination (mean difference [MD] = 2.9; 95% confidence interval [CI]: 0.7 to 5.1; P = .01), visuomotor integration (MD = 1.8; 95% CI: 0.0 to 3.7; P prematurity improved visuomotor, visuoperceptual, and visuospatial abilities at age 11 years. General intelligence, attention, and behavior were not adversely affected by caffeine, which highlights the long-term safety of caffeine therapy for apnea of prematurity in very low birth weight neonates.

Studies of cranial ultrasonography and early childhood outcomes among cohorts of extremely preterm neonates have linked periventricular-intraventricular hemorrhage and cystic periventricular leukomalacia with adverse neurodevelopmental outcomes. However, the association between nonhemorrhagic ventriculomegaly and neurodevelopmental and behavioral outcomes is not fully understood. To characterize the outcomes of extremely preterm neonates younger than 27 weeks' gestational age who experienced nonhemorrhagic ventriculomegaly that was detected prior to 36 weeks' postmenstrual age. This longitudinal observational study was conducted at 16 centers of the Eunice Kennedy Shriver National Institute of Child Health and Human Development Neonatal Research Network. Infants born prior to 27 weeks' gestational age in any network facility between July 1, 2006, and June 30, 2011, were included if they had a cranial ultrasonogram performed prior to 36 weeks' postmenstrual age. Comparisons were made between those with ventriculomegaly and those with normal cranial sonograms. Data analysis was completed from August 2013 to August 2017. The main outcome was neurodevelopmental impairment, defined as a Bayley Scales of Infant and Toddler Development III cognitive score less than 70, moderate/severe cerebral palsy, a Gross Motor Function Classification System score of level 2 or more, vision impairment, or hearing impairment. Secondary outcomes included Bayley Scales of Infant and Toddler Development III subscores, components of neurodevelopmental impairment, behavioral outcomes, and death/neurodevelopmental impairment. Logistic regression was used to evaluate the association of ventriculomegaly with adverse outcomes while controlling for potentially confounding variables and center differences as a random effect. Linear regression was used similarly for continuous outcomes. Of 4193 neonates with ultrasonography data, 300 had nonhemorrhagic ventriculomegaly (7%); 3045 had normal cranial

To evaluate the relationship between preterm premature rupture of membranes (PPROM) and cognitive impairment in 5-year-old children born very preterm. The Etude Epidémiologique sur les Petits Ages Gestationnels Study is a population-based cohort of children followed up from birth to age 5 years recruited in 9 French regions in 1997. We analyzed data from singletons born between 24 and 32 weeks gestation categorized into 4 groups according to etiology of prematurity: infants born after PPROM, after idiopathic preterm labor, in a vascular context (Vasc), and to women with other complications (Other). Cognitive development at age 5 years was assessed using the Mental Processing Composite score of the Kaufman-Assessment Battery for Children. Among the 1051 children followed up to age 5 years, the mean Mental Processing Composite score was 93.6 ± 19.7, and 13.3% of the children (140 of 1051) had cognitive impairment. After adjustment for potential confounders, the risk of cognitive impairment among infants in the PPROM group was not significantly different than that in the idiopathic preterm labor group (OR, 1.09; 95% CI, 0.62-1.92) and the Other group (OR, 1.36; 95% CI, 0.75-2.47), but was lower than that in the Vasc group (OR, 1.86; 95% CI, 1.16-2.97). In the PPROM group, the risk of cognitive impairment was greater when the latency period (ie, time from rupture to delivery) was <3 days (OR, 2.32; 95% CI, 1.07-5.02). Preterm infants born after PPROM are not at increased risk for cognitive impairment in childhood, but the time between PPROM and birth may influence that risk. Copyright © 2013 Mosby, Inc.

Many premature infants are born without exposure to antenatal steroids (ANS) or with incomplete courses. This study evaluates the dose-dependent effect of ANS on rates of neonatal morbidities and early childhood neurodevelopmental outcomes of extremely premature infants. To compare rates of neonatal morbidities and 18- to 22-month neurodevelopmental outcomes of extremely premature infants exposed to no ANS or partial or complete courses of ANS. In this observational cohort study, participants were extremely premature infants (birth weight range, 401-1000 g; gestational age, 22-27 weeks) who were born at participating centers of the National Institute of Child Health and Human Development Neonatal Research Network between January 2006 and December 2011. Data were analyzed between October 2013 and May 2016. Rates of death or neurodevelopmental impairment at 18 to 22 months' corrected age. Neurodevelopmental impairment was defined as the presence of any of the following: moderate to severe cerebral palsy, a cognitive score less than 85 on the Bayley Scales of Infant and Toddler Development III, blindness, or deafness. There were 848 infants in the no ANS group, 1581 in the partial ANS group, and 3692 in the complete ANS group; the mean (SD) birth weights were 725 (169), 760 (173), and 753 (170) g, respectively, and the mean (SD) gestational ages were 24.5 (1.4), 24.9 (2), and 25.1 (1.1) weeks. Of 6121 eligible infants, 4284 (70.0%) survived to 18- to 22-month follow-up, and data were available for 3892 of 4284 infants (90.8%). Among the no, partial, and complete ANS groups, there were significant differences in the rates of mortality (43.1%, 29.6%, and 25.2%, respectively), severe intracranial hemorrhage among survivors (23.3%, 19.1%, and 11.7%), death or necrotizing enterocolitis (48.1%, 37.1%, and 32.5%), and death or bronchopulmonary dysplasia (74.9%, 68.9%, and 65.5%). Additionally, death or neurodevelopmental impairment occurred in 68.1%, 54.4%, and 48.1% of

Flomoxef (FMOX), an oxacephem antibiotic of beta-lactam antibiotic family, was administered to 16 infants including 6 neonates and 10 premature infants at a dose of 20 or 40 mg/kg via intravenous injection, and plasma and urinary concentrations and the urinary recovery were determined. In addition, FMOX was administered via intravenous injection at daily doses averaging 85.5 mg/kg divided into 2 to 4 times for durations averaging 9 days to 96 infants from 0- to 90-day old (mainly neonates and premature infants). In 44 of the 96 infants with bacterial infections, clinical and bacteriological efficacies were evaluated, and prophylactic effects of FMOX were determined in the remaining 52 infants. Adverse reaction and laboratory tests abnormalities were evaluated also. The obtained results are summarized as follows. 1. Upon administration of FMOX at 20 or 40 mg/kg to neonates and premature infants via intravenous injection, plasma concentrations, half-lives and AUC were determined. In 3 neonates of 5, 7 and 16 days of ages administered with 20 mg/kg of FMOX, peak plasma concentrations of 62.5 to 99.7 micrograms/ml were achieved in 5 or 15 minutes after injection. Half-lives of FMOX in these neonates were 1.48 to 1.78 hours and AUC's were 112 to 161 micrograms.hr/ml. The same dose (20 mg/kg) of FMOX was administered to 3 premature infants of 5- 16- and 19-day of ages and initial blood samples were obtained at 5 minutes after injection from the 5-day old subject and at 15 minutes after injection from the 16-and 19-day old subjects. Peak plasma concentrations of 63.6 to 79.9 micrograms/ml were observed in the samples. Half-lives were 1.69 to 2.20 hours and AUC's were 174 to 201 micrograms.hr/ml. When 3 neonates (one 17-day old and two 24-day old subjects) were administered with 40 mg/kg of FMOX, peak plasma concentrations obtained at 5 minutes after injection were 99.7 to 122.0 micrograms/ml. Half-lives were 1.28 to 1.92 hours and AUC's were 170 to 357 micrograms
essential because of the declining incidence of IVH and PHH, variations in referral patterns, and neonatal ICU and neurosurgical management. Well-designed multicenter trials will eventually produce evidence to enable neurosurgeons to provide their smallest, most vulnerable patients with the best practices to minimize perioperative complications and permanent shunt dependence, and most importantly, optimize long-term neurodevelopmental outcomes.

Full Text Available Abstract Background and objective: NAS is a combination of signs and symptoms that due to physical and mental dependency, develops in neonates born from drug addicted mothers. The onset of NAS varies in accordance with the type, amount, frequency and duration of substance used. Because of diverse and unclear pattern of substance abuse in Iranian addicted pregnant mothers in comparison with western countries, this multi-center study has been designed to evaluate NAS in neonates born from drug addicted mothers. Material and method: A cross sectional study was carried out on newborns of narcotic addicted mothers during the first six months of 2008. The newborn’s status and clinical signs were checked by physical examination and scored by the Finnegan scoring system. Results: In this study 100 neonates born from narcotic addicted mothers were examined; the most used narcotic was crack (36%. 60% of neonates showed signs of NAS. The most prevalent signs of NAS were increased muscle tonicity (60%/7, irritability (59%/6 and increased moro reflex (51%/8. Neonates born from crack abusers, in comparison with other drugs, were significantly at risk of NAS (100% vs.87%, p

Today, the first generations of very low birth weight (VLBW personality traits, associated with both psychopathological vulnerability and resilience. In this cohort study we compared personality traits among young adults (age range 18 to 27 years, mean 21.4, SD 2.19) with VLBW (n = 158) with those of term-born controls (n = 168) of same gender, age, and maternity hospital. The participants completed the Neo-Personality Inventory. Of the five main traits, the VLBW participants scored significantly higher in conscientiousness (MD .1, 95% CI .0 to .3; p personality profiles among the VLBW subjects (p assessment, parental education, individual school grade average, and maternal pre-eclampsia and smoking during pregnancy. Young adults born with VLBW showed markedly different personality traits compared with their controls. The VLBW group displayed less negative emotions, were more dutiful and cautious, and displayed more warmth in their social relationships than their term-born peers. We present two potential mechanisms underlying these findings. The first relates to parental influences and the other to evidence linking biological mechanisms associated with prematurity with personality characteristics in adulthood.
Conclusion: Abnormal brain sonography [odds ratio (OR: 2.222, p = 0.047 and necrotizing enterocolitis (NEC (OR: 2.857, p = 0.017 did affect the first trial in the study group. Early intervention of oral-motor management in very-low-birth-weight premature infants improved feeding performance and neonatal outcome in terms of shorter hospital days. Abnormal brain image and NEC could interfere with the success rate of initial challenge of transitioning from tube to oral feeding in the study group.

To identify predictors of severe retinopathy of prematurity (ROP) in a large population-based cohort and to examine risk-adjusted variations across units. Retrospective analysis of Canadian Neonatal Network data on neonates with birth weight <1500 g who were screened for ROP between 2003 and 2010. Characteristics of infants with and without ROP were compared and a risk-adjusted model for severe ROP was developed. Rates of severe ROP were compared between sites. 1163 of 9187 (12.7%) infants developed severe ROP. Lower gestational age, male sex, small for gestational age, patent ductus arteriosus, late onset sepsis, more than two blood transfusions, inotrope use, and outborn status were associated with an increased risk of severe ROP. Severe ROP rates varied significantly between units. Younger, smaller and sicker male infants had higher adjusted risks of severe ROP and rates varied significantly among sites.

More than 50% of women worldwide give birth at home, but little is known about home birth and subsequent neonatal hospitalisation. The objective of the study was to investigate home birth and neonatal hospitalisation of term neonates in Peru. The relationship between birth setting [home - with or without skilled birth attendant (SBA), health centre, hospital] and neonatal hospitalisation (n = 1656) and incubator care (n = 1651) was investigated using data from the 2002 Young Lives Study. Infants were sampled from 20 sentinel sites across Peru. At each sentinel site 100 households with children aged 6-18 months were randomly sampled (therefore the sample only captured children surviving to 6 months of age). Multivariate regression modelling was used with models adjusted for a range of demographic and clinical factors. After adjustment, the odds of hospitalisation were lower in neonates born at home (with SBA OR 0.20, 95% CI 0.0-0.8, p = 0.021; without SBA OR = 0.4, 95% CI 0.2-0.7, p = 0.002) than in those born in hospital. Socio-demographic factors such as ethnicity, rural living, education, socio-economic status and access to transport did not influence neonatal hospitalisation, time in hospital, incubator care or time under incubator care. Neonates born at home were less likely to be hospitalised after birth owing to neonatal morbidity than neonates born in hospital. It is unclear whether this finding reflects poorer accessibility to hospital care for neonates born at home, or if neonates born at home required hospitalisation less frequently than neonates born in hospital owing to lower neonatal morbidity or other factors such as lower rates of medical intervention for home births. Further research is needed to explore the underlying mechanisms of these findings.
Full Text Available Introduction: Retinopathy of prematurity (ROP is a vasoproliferative disorder of the retina of preterm newborns and is an important and preventable cause of visual impairment in childhood. This study aimed to assess the incidence and main risk factors associated with the development of ROP in the last 10 years at Hospital Prof. Doutor Fernando Fonseca in Lisbon, Portugal.Methods: Observational and retrospective study conducted between 2005 and 2014 at Hospital Prof. Doctor Fernando Fonseca. The study included newborns of gestational age < 32 weeks. We analyzed maternal, prenatal and neonatal factors associated with the development of ROP. Statistical analysis were performed with Statistical Package for Social Sciences (SPSS® software. Univariate and multivariate analyses were performed and a multiple logistic regression model was carried out with a significance level α = 0.05.Results: 527 premature infants with a gestational age < 32 weeks were studied, of which 165 developed ROP. 60 of these patients needed treatment. In the univariate analysis, the risk factors for the development of ROP were maternal infection in pregnancy, low birth weight, low gestational age, low Apgar score at 5 minutes, need for oxygen therapy until the 28th day of life, a high score on the CRIB and SNAPPE2 scales, use of surfactant, respiratory distress syndrome, persistence of patent ductus arteriosus, peri-intraventricular hemorrhage and neonatal sepsis. In the multiple logistic regression analysis, risk factors for ROP were the presence of neonatal sepsis, respiratory distress syndrome, persistence of patent ductus arteriosus and a high score on the neonatal SNAPPE2 scale.Conclusions: We found a ROP incidence rate of 31.3%, with risk factors similar to those observed in other studies.
Full Text Available Background: After the umbilical cord is cut, premature neonates face numerous problems including hypothermia. With regard to serious complications of hypothermia and incapability of conventional methods in preservation of neonates′ temperature after admission, the researcher decided to conduct a study on the effects of two polyethylene covers in prevention of hypothermia among premature neonates. Materials and Methods: This clinical trial was conducted on 96 neonates aged 28-32 weeks that randomly allocated, by drawing of lots, to three 32-subject groups as follows: Intervention group 1 (a plastic bag cover and a cotton hat, intervention group 2 (a plastic bag cover and a plastic hat, and a control group receiving routine care. Data were analyzed by descriptive and inferential statistics through SPSS V.14. Results: Mean axillary temperatures in intervention groups 1 and 2 were different after admission and 1 and 2 h later, but this difference was not significant and the mean axillary temperature increased with time. Mean axillary temperature in the control group showed no significant difference at these time points and it did not increase with time. The mean temperatures in preterm infants were significantly higher in the intervention groups after admission and 1 and 2 h after birth, compared to the control group. Mean axillary temperature in intervention group 2 was significantly higher than in intervention group 1. Conclusions: Usage of a plastic bag cover and a plastic hat (with no risk of hyperthermia is more effective in preventing hypothermia among neonates aged 28-32 weeks, compared to usage of a plastic bag cover and a cotton hat.

Premature neonates' feeding is of great importance due to its effective role in their growth. These neonates should reach an independent oral nutrition stage before being discharged from the Neonatal Intensive care Unit. Therefore, the researcher decided to conduct a study on the effect of palady and cup feeding on premature neonates' weight gain and their reaching full oral feeding time interval. This is a clinical trial with a quantitative design conducted on 69 premature infants (gestational age between 29 and 32 weeks) who were assigned to cup (n = 34) and palady (n = 35) feeding groups through random allocation. The first feeding was administrated either by cup or palady method in each shift within seven sequential days (total of 21 cup and palady feedings). Then, the rest of feeding was administrated by gavage. Mean hospitalization time (cup = 39.01 and palady = 30.4; P cup = 33.7 and palady = 24.1; P cup group. Mean weight changes of neonates 7 weeks after the intervention compared to those in the beginning of the intervention were significantly more in palady group compared to the cup group (cup = 146.7 and palady = 198.8; P cup group. Subjects' weight gain was also higher in palady group compared to the cup group. Premature neonates with over 30 weeks of gestational age and physiological stability can be fed by palady.

The aim of the present study was to evaluate the effects of antibiotics on the condition of babies born with risk of neonatal sepsis. From March, 2014 to February, 2015, 200 neonates born with risk factors of septicemia in the Neonatal Intensive Care Unit at Xuzhou Central Hospital, were enrolled in the present study. Venous blood samples were collected within 6 h of birth using aseptic technique. Part of the blood specimens were cultured using BACTEC PEDS PLUS/F Culture Vials. Subsequently, the subcultures were prepared from each presumptive positive vial and bacterial isolates were identified. The remaining portion was used to measure the level of C-reactive protein (CRP) and total leukocyte count (TLC). The result showed that 32% of neonates were infected, of whom, 21.9% had Staphylococcus aureus , 21.9% had Acinetobacter Baumanni , and 12.5% had Klebsiella pneumoniae . Additionally, Staphylococcus epidermis , Enteroccus spp ., Pseudomonas aeruginosa and E. coli was isolated from 9.4, 7.8, 6.3 and 4.7% of neonates, respectively. The neonates enrolled in the present study had ≥1 risk factor for neonatal sepsis, and the average number of risk factors was 1.95 per neonate. Neonates (39.1%) with positive blood culture results, had a CRP level >0.8 mg/dl, and 12.5% was shown to have an abnormal increase in their leukocyte counts. The association between leukocyte counts and blood culture results was not statistically significant. Of the neonates with positive blood cultures 45.3% died within 7 days after birth, while there was no mortality among those with negative culture results. The results indicate that in the presence of risk factors for sepsis, irrespective of clinical features of septicemia, neonatal sepsis screening should be performed. Rational and appropriate use of antibiotics may minimize the emergence of multidrug resistant bacteria in neonatal units.

AIM: To compare anxiety symptoms in adolescents born extremely prematurely to term-born controls. METHODS: We had 96 preterm-born adolescents and 40 term-born controls from Denmark, and their mothers score the adolescents on the Revised Children Anxiety and Depression scale. We analysed group...... differences, cross-informant correlations and relative risks for elevated anxiety symptoms. RESULTS: Self-reported anxiety symptoms did not significantly differ, although the upper confidence limit (95% CI: -3.3 to 5.1) supported an odds ratio of 2 for the preterm-born participants. Mothers of the preterm......-born participants reported higher social anxiety symptoms than did mothers of controls (51.7 versus 46.8, p = 0.001). The relative risk for being above a threshold indicating distressing anxiety was small from self-reports (1.39; p = 0.60). From mother-reports, the relative risk was noticeable but not significant...

Inadequate nutrition supply during the period of intrauterine growth and the first year of life leads to persistent metabolic changes and provokes development of various diseases. Тo compare physical development, body composition, and hormonal status (insulin, insulin-like growth factor-1 (IGF-1), somatotropic hormone (STH), C-Peptide, cortisol) indices in premature infants born with intrauterine growth restriction (IUGR) at the term corrected age with the same indices in mature infants with IUGR and premature infants with weight appropriate for their gestational age (GA). А crossover study of anthropometric measures, body composition and growth hormones changes assessment was carried out. It included 140 premature infants with weight appropriate for their GA, 58 premature infants with IUGR and 64 mature infants with IUGR. Anthropometric measures were assessed with Fenton and Anthro growth charts (WHO, 2009); body composition was studied with the air plethysmography method (РЕA POD, LMi, USA). Level of hormones in blood serum was assessed with biochemical methods. It is found that anthropometric measures in premature infants with weight appropriate for their GA and premature infants with IUGR at the term corrected age did not have any significant differences while premature infants with IUGR tended to have lower weight. Studying body composition we found that both groups of premature infants had slightly higher level of fat mass in comparison with mature infants. High concentration of insulin, cortisol, IGF-1, and C-peptide was found in premature and mature infants with IUGR. Instead, lower levels of STH was found in infants with IUGR. Formula fed premature infants (comparing to breastfed ones) had higher levels of fat mass, insulin, IGF-1, and C-peptide. Mature infants with IUGR did not tend to have the correlation between levels of fat mass, insulin, IGF-1, C-peptide, and type of feeding. Not only insufficient intrauterine growth but also nutrition pattern

Children born very prematurely (pain-related stress during neonatal intensive care has been proposed to contribute to altered neurocognitive development in these children. Due to critical periods in the development of thalamocortical systems, the immature brain of infants born at extremely low gestational age (ELGA; pain. In a cohort of school-age children followed since birth we assessed relations between functional brain activity measured using magnetoencephalogragy (MEG), visual-perceptual abilities and cumulative neonatal pain. We demonstrated alterations in the spectral structure of spontaneous cortical oscillatory activity in ELGA children at school-age. Cumulative neonatal pain-related stress was associated with changes in background cortical rhythmicity in these children, and these alterations in spontaneous brain oscillations were negatively correlated with visual-perceptual abilities at school-age, and were not driven by potentially confounding neonatal variables. These findings provide the first evidence linking neonatal pain-related stress, the development of functional brain activity, and school-age cognitive outcome in these vulnerable children.

Over the last 20 years, 640 premature newborns with alterations in suction-deglution have been taken care of in the neonatal intensive care unit at the Hospital Infantil de México Federico Gómez, using techniques for patients with immaturity, and neurological, gastrointestinal, cardiologic and respiratory pathologies. This descriptive study includes the treatment employed mainly in premature newborns during this period. Suction, swallowing and breathing coordination are some of the most complex abilities that premature newborns face, due to their anatomofunctional immaturity and improper sensoriomotor integration for the high energy requirements they must meet. Sucking and swallowing are voluntary and involuntary processes that guarantee the safe passage of food from mouth to stomach, and require the coordination of the cranial nerves, the brain stem and cerebral cortex and muscles of the mouth, pharynx and esophagus. The rehabilitation treatment consists in the positioning of the newborn and caretaker, adaptation of teat, regulation of muscle tone and progressive intake of milk. The feeding processing was reduced to 1.5 weeks in newborns submitted to treatment, whereas in those who did not receive the treatment, the proccess took up to 3 weeks. Copyright: © 2018 Permanyer.

Purpose. Because of frequent radiological investigations performed in 1 neonatal intensive care unit, a dosimetry study was carried out to assess the level of doses received by premature babies. Materials and methods. In vivo measurements were performed and effective doses were evaluated for single radiographs. Individual cumulative doses received over the period of stay were then estimated, for each premature baby entering the intensive care unit in 2002, taking into account the number of radiographs they underwent. Results. On average, babies stayed for a week and more than one radio-graph was taken per day. Results showed that, even if average doses per radiograph were relatively low (25μSv), cumulative doses strongly depended on the length of stay, and can reach a few mSv. Conclusion. Even if doses per radiograph are in agreement with European recommendations, optimisation of doses is particularly important because premature babies are more sensitive to radiation than adults and because they usually undergo further radiological examinations in other services. On the basis of the results of this dosimetry study, the implementation of a larger study is being discussed. (author)

Surgical closure of patent ductus arteriosus in premature neonates is an aggressive technique and is not free of complications. A study was designed with the aim of describing our experience with a less invasive technique, the extra-pleural approach via a posterior minithoracotomy, and to compare the results with the classic transpleural approach. A retrospective cohort study was conducted on premature neonates on whom surgical closure of the ductus was performed during a ten-year period (March 2005 to March 2015). A comparison was made of the acute complications, the outcomes on discharge, and follow-up, between the extra-pleural approach and the classic transpleural approach. The study included 48 patients, 30 in the classical approach and 18 in the extra-pleural group. The demographic and pre-operative characteristics were similar in both groups. No differences were found between the 2 groups in the incidence of acute post-operative complications (56.6 vs. 44.4%), on the dependence on oxygen at 36 weeks (33.3 vs. 55.5%), or in hospital mortality (10 vs. 16.6%). As regards the short-term progress, the extra-pleural group required fewer days until the withdrawal of supplementary oxygen (36.3 vs. 28.9) and until hospital discharge (67.5 vs. 53.2), although only the time until extubation achieved a statistically significant difference (11.5 vs. 2.7, P=.03). The extra-plural approach by posterior minithoracotomy for the surgical closure of ductus in the premature infant is viable and could bring some clinical benefits in the short-term.

Full Text Available Background: Premature birth may complicate the development and quality of the mother–infant attachment relationship. Music and kangaroo care are two common complementary cares performed in the neonatal intensive care unit (NICU. The present study investigated the effect of kangaroo care combined with music on the mother–premature neonate attachment. Materials and Methods: In this clinical trial, 64 mothers with premature neonates were selected and assigned to the control and study groups through random allocation. In the control group, kangaroo care, and in the study group, kangaroo care combined with music was adopted. The level of mother–premature neonate attachment was measured and compared before and after the intervention in both the groups using Avant's Maternal Attachment Assessment Scale. Results: There was a significant increase in the mean overall score of attachment in the kangaroo care combined with music group (70.72 (11.46 after the intervention compared to the kangaroo care without music group (53.61 (9.76. Conclusions: The mean overall score of mother–neonate attachment in the kangaroo care combined with music group was higher than the kangaroo care group. This difference can be related to the effectiveness of music combined with kangaroo care.

To establish normative data for stretched penile length (SPL) in term male neonates born in Tamil Nadu. All live term male neonates delivered in a hospital during a given period were included. SPL was measured from the pubic ramus to the tip of the glans. Two consecutive measurements were taken and average was recorded. The mean SPL observed in our study was 2.83 ± 0.49 cm. This study helps establish normative values for SPL in neonates of Tamil Nadu origin.
Full Text Available Backgrounds & aim: Early diagnosis of developmental delays in children with high risk history of hospitalization in the intensive care unit is essential. Children with one or more risk factors before or around birth are more at risk for developmental delay. The aim of this study was to determine the evolution and history of premature children admitted to the neonatal intensive care unit. Methods: the present descriptive study was conducted on 80 premature children admitted to the neonatal intensive care unit of the Imam Sajad (AS hospital, Yasuj, Iran, with a history of developmental delay at the ages of 4, 6.12 months using the ASQ questionnaire. The questionnaire contains 30 questions including five fields such as communication, gross motor, fine motor, social-personal, problem solving. Along with questionnaire, other essential information were completed. The collected data were analyzed using Chi-square test. Results: among 80 patients, 43 cases (53.8 % were male, with an average weight of 1734.37+-445.50 gr. Regarding communication, gross motor, fine motor, social-personal, problem solving, the results were abnormal at the rate of 10, 30, 27.5, 23.8 and 23.8% respectively. There was no significant relationship found among different fields of development, birth weight, gestational age and Apgar score a significant relationship was found. A significant relationship between infants born through normal delivery and infants born via Caesarean section was realized (p<0.05. Conclusion: Despite the natural evolution, the majority of premature children with a history of NICU admission, a significant number have developmental disorder and need to consider early to avoid complications in the future.

Caffeine treatment is widely used in nursing care to reduce the risk of apnoea in premature neonates. To check the therapeutic efficacy of the treatment against apnoea, caffeine concentration in blood is an important indicator. The present study was aimed at building a pharmacokinetic model as a basis for a medical decision support tool. In the proposed model, time dependence of physiological parameters is introduced to describe rapid growth of neonates. To take into account the large variability in the population, the pharmacokinetic model is embedded in a population structure. The whole model is inferred within a Bayesian framework. To update caffeine concentration predictions as data of an incoming patient are collected, we propose a fast method that can be used in a medical context. This involves the sequential updating of model parameters (at individual and population levels) via a stochastic particle algorithm. Our model provides better predictions than the ones obtained with models previously published. We show, through an example, that sequential updating improves predictions of caffeine concentration in blood (reduce bias and length of credibility intervals). The update of the pharmacokinetic model using body mass and caffeine concentration data is studied. It shows how informative caffeine concentration data are in contrast to body mass data. This study provides the methodological basis to predict caffeine concentration in blood, after a given treatment if data are collected on the treated neonate.

A neonatal mouse model of intermittent hypoxia (IH) simulating the recurring hypoxia/reoxygenation episodes of apnea of prematurity (AOP) was developed. C57BL/6 P2 pups were culled for exposure to either intermittent hypoxia or intermittent air as control. The IH paradigms consisted of alternation cycles of 20.9% O2 and either 8.0% or 5.7% O2 every 120 or 140s for 6h a day during daylight hours from day 2 to day 10 postnatally, i.e., roughly equivalent to human brain development in the perinatal period. IH exposures elicited modest to severe decrease in oxygen saturation along with bradycardia in neonatal mice, which were severity-dependent. Hypomyelination in both central and peripheral nervous systems was observed despite the absence of visible growth retardation. The neonatal mouse model of IH in this study partially fulfills the current diagnostic criteria with features of AOP, and provides opportunities to reproduce in rodents some of the pathophysiological changes associated with this disorder, such as alterations in myelination.

To assess the number of children born with microcephaly in the State of Paraíba, north-east Brazil. We contacted 21 maternity centres belonging to a paediatric cardiology network, with access to information regarding more than 100 000 neonates born between 1 January 2012 and 31 December 2015. For 10% of these neonates, nurses were requested to retrieve head circumference measurements data from delivery-room books. We used three separate criteria to classify whether a neonate had microcephaly: (i) the Brazilian Ministry of Health proposed criterion: term neonates (gestational age ≥ 37 weeks) with a head circumference of less than 32 cm; (ii) Fenton curves: neonates with a head circumference of less than -3 standard deviation for age and gender; or (iii) the proportionality criterion: neonates with a head circumference of less than ((height/2))+10) ± 2. Between 1 and 31 December 2015, nurses obtained data for 16 208 neonates. Depending on which criterion we used, the number of neonates with microcephaly varied from 678 to 1272 (4.2-8.2%). Two per cent (316) of the neonates fulfilled all three criteria. We observed temporal fluctuations of microcephaly prevalence from late 2012. The numbers of microcephaly reported here are much higher than the 6.4 per 10 000 live births reported by the Brazilian live birth information system. The results raise questions about the notification system, the appropriateness of the diagnostic criteria and future implications for the affected children and their families. More studies are needed to understand the epidemiology and the implications for the Brazilian health system.

Fourteen cranial US studies were performed in each of 31 premature neonates weighing 600-1,250 gm. The studies revealed a 61% incidence of intracranial hemorrhage (ICH). Forty-two percent had occurred by age 6 hours and 95% bu age 5 days. These control data were confirmed in patients given prophylactic indomethacin. Forty-eight infants weighing less than 1,250 gm were randomly assigned to treatment with indomethacin (0.5 mg/kg/12 hours given intravenously for five treatments) or a placebo at 6 hours of life. Cardiac US disclosed patent ductus arteriosus in 82% of patients at 6 hours, with subsequent closure in 84% of the treated group and in 60% of the controls. ICH occurred in 25% of the treated infant and in 58% of the controls. The authors conclude that indomethacin therapy can reduce the incidence of ICH, but requires careful sonographic monitoring by US

Full Text Available Background: Respiratory distress syndrome is one of the main complications associated with low birth weight, and a main cause of mortality in premature neonates. The present study aimed to compare the efficacy of ventilator continuous positive airway pressure (CPAP and bubble CPAP in the treatment of respiratory distress syndrome (RDS in premature neonates. Methods: This randomized controlled clinical trial was conducted on 119 neonates diagnosed with RDS, with the gestational age of 28-34 weeks and birth weight of 1000-2200 grams, who were admitted in the neonatal intensive care unit (NICU. Infants were allocated to two groups of ventilator CPAP (VCPAP and bubble CPAP (BCPAP therapy. Results: Mean weight, gestational age, and one-minute Apgar score were not significantly different between the two groups. However, duration of treatment with mechanical ventilation in the BCPAP group was significantly lower compared to the VCPAP group. In addition, frequency of complications had no significant difference between the two groups. Conclusion: In the treatment of RDS, duration of mechanical ventilation was lower in the BCPAP group compared to the VCPAP group in premature neonates

To analyze the incidence and severity of retinopathy of prematurity (ROP) in China, and to explore the workload implications of applying different criteria. A prospective, neonatal units-based study undertaken in two tertiary level hospitals in Shanghai, China, from January 1, 2010 to December 31, 2012. All infants with birth weight (BW) of 2000 g or less and/or gestational age (GA) of 34 weeks or less were screened for ROP. Retinopathy of prematurity was classified using the international classification, and was treated in accordance with the recommendations of the Early Treatment for Retinopathy of Prematurity Cooperative Group. A total of 2825 (93.7%) of 3014 eligible infants were screened, and ROP was diagnosed in 503 infants (17.8%). One hundred ninety-one infants (6.8%) had type 1 or worse ROP and were treated with laser or vitrectomy. The mean GA of ROP patients was 29.9 ± 2.1 weeks and their mean BW was 1425 ± 266 g. Infants who needed treatment for ROP had a mean GA of 29.3 ± 2.1 weeks and mean BW of 1331 ± 330 g. Among these treated infants, 18 infants (9.4%) exceeded the United Kingdom's (UK) screening criteria, and 28 (14.7%) exceeded the criteria used in the United States (US). If narrower criteria, as in GA less than or equal to 33 weeks and/or BW less than or equal to 1750 g were adopted, almost 16.9% fewer infants would not have been examined, with no infant missing treatment. Larger, older infants are at risk in China and screening criteria used in the US and UK may not be suitable for China. Further population-based studies are recommended to determine the necessity of modifying the current ROP screening protocol.

To examine the effect of an educational intervention on parental readiness for premature infant discharge from neonatal intensive care units. Low readiness for discharge can result in negative healthcare outcomes for infants and their parents. However, few studies have examined the effect of discharge education programmes on parental readiness for premature infant discharge in Chinese critical care settings. A quasi-experimental study. Between October 2011-March 2012, 154 parents of premature infants were recruited from neonatal intensive care units of two tertiary hospitals in Central China. These parents were assigned to either the intervention or control group based on their entry order. Parents in the intervention group received two sessions of 60-minute discharge education along with hospital routine care; parents in the control group only received hospital routine care. Parental readiness for discharge and quality of discharge education were assessed on the day of infant discharge from neonatal intensive care units. Independent samples t-test and linear regression were used to analyse the data. Parental readiness for premature infant discharge was in the moderate level. Independent samples t-test showed that both mean scores of parental discharge readiness and discharge teaching quality from the intervention group were significantly higher than those in the control group. Linear regression analysis showed that discharge teaching quality explained 39·7% of the variance in parental readiness for premature infant discharge. Discharge education can improve parental readiness for premature infant discharge. Quality of discharge teaching can significantly predict parental readiness for premature infant discharge. © 2015 John Wiley & Sons Ltd.

To evaluate the relationships between optic nerve head blood flow, expressed as mean blur rate (MBR) measured by laser speckle flowgraphy (LSFG), and photocoagulation therapy in neonates with retinopathy of prematurity (ROP). Case series study. We studied 5 ROP neonates either during sleep or under sedation both before and after photocoagulation, and evaluated 8 eyes in which the circulation could be measured three times consecutively. Correlations between the MBR-A (mean of all values), MBR-V (vessel mean) and MBR-T (tissue mean) and postmenstrual age were evaluated using Spearman's rank correlation coefficient. In addition, correlations between the relative MBR (-A, -V, -T) value and number of photocoagulation burns and the NV score were evaluated. Differences between post-treatment MBR in ROP subjects and normal neonates' MBR were estimated using analysis of covariance (ANCoVA), with adjustment for postmenstrual age. The relative MBR (-A, -V, -T) values after photocoagulation were 69.6 ± 16.0%, 66.7 ± 17.0% and 74.3 ± 14.6%, respectively. Postmenstrual age was significantly correlated with post-treatment MBR-A (r = 0.83, p = 0.0101), MBR-V (r = 0.85, p = 0.007) and MBR-T (r = 0.76, p = 0.0282). The relative MBR-T value was significantly correlated with the number of photocoagulation burns (r = -0.75, p = 0.033) and NV score (r = -0.72, p = 0.0437). The ANCoVA results showed no significant difference between post-treatment MBR and normal neonates' MBR. Photocoagulation improved the dilation of veins and tortuosity of arteries and reduced ocular blood flow in ROP subjects. Since the post-treatment MBR was not different from a normal neonate's MBR, it is suggested that the pre-treatment MBR was higher in severe ROP cases.

The objective of this study is to identify possible perinatal risk factors related to intraventricular hemorrhage (IVH) in preterm infants born at 34 weeks of gestation or less following preterm premature rupture of membranes (pPROM). A total of 292 preterm infants born at 34 weeks of gestation or less following pPROM were enrolled in the study, while 155 newborns with incomplete data, especially those that lack histological examination of the placenta, maternal details, and neonatal characteristics, have been further excluded. Finally, data of 137 preterm infants were included in the analysis. All infants underwent ultrasonographic screening for IVH. Thirty-three infants with IVH were considered as cases and 104 infants without IVH were considered as controls. The association between risk factors and IVH was evaluated by univariate and multivariate logistic regression analyses. The incidence of IVH in preterm infants born at 34 weeks of gestation or less following pPROM was 24.1%, while the incidence of maternal chorioamnionitis was 43.8%. By univariate analysis, gestational age, birth weight, asphyxia resuscitation, maternal chorioamnionitis, fetal distress, amniotic fluid index, and latency of the rupture of membranes to birth were found to be significantly different between the 2 groups. By logistic regression analysis, lower gestational age, low birth weight, asphyxia resuscitation, and maternal chorioamnionitis were found to be independent risk factors for IVH. Lower gestational age, low birth weight, asphyxia resuscitation, and maternal chorioamnionitis are independent risk factors for IVH in preterm infants born at 34 weeks of gestation or less following pPROM.

To report the reduction in the incidence and severity of retinopathy of prematurity (ROP) in rural India over a 4-year period following the introduction of improved neonatal care practices. The Karnataka Internet Diagnosis of Retinopathy of Prematurity program (KIDROP), is a tele-medicine network that screens for ROP in different zones of Karnataka state in rural India. North Karnataka is the most underdeveloped and remote zone of this program and did not have any ROP screening programs before the intervention of the KIDROP in 2011. Six government and eleven private neonatal centers in this zone were screened weekly. Specific neonatal guidelines for ROP were developed and introduced in these centers. They included awareness about risk factors, oxygen regulation protocols, use of pulse oxymetry, monitoring postnatal weight gain, nutritional best practices, and management of sepsis. The incidence and severity of ROP were compared before the guidelines were introduced (Jan 2011 to Dec 2012) and after the guidelines were introduced (July 2013 to June 2015). During this 4-year period, 4,167 infants were screened over 11,390 imaging sessions. The number of enrolled infants increased from 1,825 to 2,342 between the two periods ( P large, unscreened burden of ROP. Improving neonatal care in these centers can positively impact the incidence and severity of ROP even in a relatively short period. A combined approach of a robust ROP screening program and improved neonatal care practices is required to address the challenge.

To verify the reliability and safety of transcutaneous bilirubin (TcB) measurements in patched skin areas in neonates born extremely preterm under phototherapy. Sixty neonates (bilirubin (TSB), lactate, pH, hemoglobin, and skin temperature were measured within 10 minutes of the TcB assay. Clinicians were blinded to TcB values, and clinical decisions about phototherapy were made with the TSB measurement only. TcB and TSB significantly were correlated (r = 0.84; P bilirubin passage. TcB overestimated TSB, and this may expose infants born preterm to unnecessary phototherapy, although it could spare approximately 65% of TSB assays. Copyright © 2017 Elsevier Inc.

Full Text Available Efficacy of antenatal corticosteroids before 25 weeks of gestation is unclear.To assess and compare neonatal outcomes following ANC exposure at 22, 23 and 24 weeks of gestation by conducting systematic review and meta- analysis.A systematic review of randomised controlled trials (RCT and non-RCTs reporting on neonatal outcomes after exposure to ANC up to 246 weeks of gestation using the Cochrane systematic review methodology. Databases Pubmed, CINAHL, Embase, Cochrane Central library, and online abstracts of conference proceedings including the Pediatric Academic Society (PAS were searched in Feb 2017. Primary outcome was in-hospital mortality defined as death before discharge during the first admission. Secondary outcomes included severe intraventricular hemorrhage (IVH> grade III and IV/or periventricular leukomalacia (PVL, necrotising enterocolitis (NEC >stage II and chronic lung disease (CLD. Meta-analysis was performed using a random-effects model. The level of evidence (LOE was summarised using the GRADE guidelines.There were no RCTs; 8 high quality non-RCTs were included in the review. Meta-analysis showed reduction in mortality [N = 10109; OR = 0.47(0.39-0.56, p<0.00001; LOE: Moderate] and severe IVH and PVL [N = 5084; OR = 0.71(0.61-0.82, p<0.00001; LOE: Low] after exposure to ANC in neonates born <25 weeks. There was no significant difference in CLD [N = 4649; OR = 1.19(0.85-1.65 p = 0.31; LOE: Low] and NEC [N = 5403; OR = 0.95 (0.76-1.19 p = 0.65; LOE: Low]. Mortality was comparable in neonates born at 22, 23 or 24 weeks.Moderate to low quality evidence indicates that exposure to ANC is associated with reduction in mortality and IVH/or PVL in neonates born before 25 weeks.

Advances in perinatal care have improved the survival rate for very low-birthweight (VLBW) infants in China. The incidence of bronchopulmonary dysplasia (BPD), however, has not been reduced. The objective of the present study was to identify the perinatal risk factors for BPD in neonates born at ≤ 1500 g. A retrospective analysis of data for neonates born at ≤ 1500 g between 1999 and 2009 in the neonatal intensive care unit (NICU) of Second Affiliated Hospital of Sun Yat-Sen University, Guangzhou city, China, was carried out. Out of a total of 11,506 live births, 3538 infants were admitted to level II nursery and NICU (level III nursery). Among 149 preterm infants born at ≤ 1500 g, 77.8% survived until day 28, and the incidence of BPD was 48.3%. Logistic regression analysis showed that gestational age (GA) ≤ 30 weeks (odds ratio [OR], 9.507; 95% confidence intervals [95%CI]: 2.604-34.707), maternal chorioamnionitis (OR, 41.987; 95%CI: 6.048-291.492), ventilation-associated pneumonia (OR, 11.600; 95%CI: 2.847-47.268), and more than three blood transfusions (OR, 10.214; 95%CI: 2.191-47.623) were associated with the development of BPD. Clinical evidence has been provided for possibly significant risk factors associated with BPD in neonates born at ≤ 1500 g, which can provide useful information for further research to improve survival of VLBW infants and decrease the incidence of BPD. © 2011 The Authors.

The hemodynamic functional response is used as a reliable marker of neuronal activity in countless studies of brain function and cognition. In newborns and infants, however, conflicting results have appeared in the literature concerning the typical response, and there is little information on brain metabolism and functional activation. Measurement of all hemodynamic components and oxygen metabolism is critical for understanding neurovascular coupling in the developing brain. To this end, we combined multiple near infrared spectroscopy techniques to measure oxy- and deoxy-hemoglobin concentrations, cerebral blood volume (CBV), and relative cerebral blood flow (CBF) in the somatosensory cortex of 6 preterm neonates during passive tactile stimulation of the hand. By combining these measures we estimated relative changes in the cerebral metabolic rate of oxygen consumption (rCMRO2). CBF starts increasing immediately after stimulus onset, and returns to baseline before blood volume. This is consistent with the model of pre-capillary arteriole active dilation driving the CBF response, with a subsequent CBV increase influenced by capillaries and veins dilating passively to accommodate the extra blood. rCMRO2 estimated using the steady-state formulation shows a biphasic pattern: an increase immediately after stimulus onset, followed by a post-stimulus undershoot due to blood flow returning faster to baseline than oxygenation. However, assuming a longer mean transit time from the arterial to the venous compartment, due to the immature vascular system of premature infants, reduces the post-stimulus undershoot and increases the flow/consumption ratio to values closer to adult values reported in the literature. We are the first to report changes in local rCBF and rCMRO2 during functional activation in preterm infants. The ability to measure these variables in addition to hemoglobin concentration changes is critical for understanding neurovascular coupling in the developing

Lung MRI volumetrics may be valuable for fetal assessment following early preterm premature rupture of the foetal membranes (pPROM). To evaluate the predictive value of MRI lung volumetrics after pPROM. Retrospective cohort study of 40 fetuses after pPROM in a large, tertiary, perinatal referral center. Fetuses underwent MRI lung volumetrics. Estimated lung volume was expressed as percentage of expected lung volume (our own normal references). Primary outcome was neonatal mortality due to respiratory distress before discharge from hospital. Gestational age range was 16-27 weeks. Estimated-to-expected lung volume was 73% in non-survivors and 102% in survivors (P < 0.05). There were no survivors with a lung volume less than 60% of expected. By logistic regression, mortality could be predicted with a sensitivity of 80%, specificity of 86% and accuracy of 85%. Fetal MR lung volumetrics may be useful for predicting mortality due to respiratory distress in children with early gestational pPROM. (orig.)

Background: Recently, the dual-side readout technique has been introduced in computed radiography, leading to an increase in detective quantum efficiency (DQE) compared with the single-side readout technique. Purpose: To evaluate if the increase in DQE with the dual-side readout technique results in a higher clinical image quality in chest radiography of premature neonates at no increase in radiation dose. Material and Methods: Twenty-four chest radiographs of premature neonates were collected from both a single-side readout technique system and a double-side readout technique system. The images were processed in the same image-processing station in order for the comparison to be only dependent on the difference in readout technique. Five radiologists rated the fulfillment of four image quality criteria, which were based on important anatomical landmarks. The given ratings were analyzed using visual grading characteristics (VGC) analysis. Results: The VGC analysis showed that the reproduction of the carina with the main bronchi and the thoracic vertebrae behind the heart was better with the dual-side readout technique, whereas no significant difference for the reproduction of the central vessels or the peripheral vessels could be observed. Conclusions: The results indicate that the higher DQE of the dual-side readout technique leads to higher clinical image quality in chest radiography of premature neonates at no increase in radiation dose.

Full Text Available Background: Congenital abnormalities are an important cause of morbidity and mortality in neonates. This study was conducted to determine the incidence of obvious congenital abnormalities in live neonates and the relationship between these abnormalities and some important factors in live newborns in Rasht hospitals. Methods: In this cross-sectional study, all live neonates born in maternity hospitals of Rasht were investigated for the presence of apparent congenital abnormalities. The data recorded in the patients’ files, including the information of parents, neonate and the type of abnormality were collected. Data were analyzed by SPSS (version 16. Results: From 1824 live neonates, 77 cases (4.2% had congenital abnormalities. The most common diagnosed abnormalities were musculoskeletal (37.7%, genital (16.9%, urinary (13%, cardiovascular (13%, and nervous system (10.4% anomalies. The increased incidence of congenital abnormalities was correlated with gestational age, route of pregnancy, history of maternal disease and drug consumption during pregnancy (P<0.0001. No significant relationship was found between abnormalities and sex, birth weight, age of parents, and consanguineous marriage. Conclusion: As gestational age, route of pregnancy, history of maternal disease and drug consumption during pregnancy were significantly associated with the increased incidence of congenital abnormalities in this region, it is necessary to pay more attention to the risk factors and the approach to control them.

Purpose To report the reduction in the incidence and severity of retinopathy of prematurity (ROP) in rural India over a 4-year period following the introduction of improved neonatal care practices. Methods The Karnataka Internet Diagnosis of Retinopathy of Prematurity program (KIDROP), is a tele-medicine network that screens for ROP in different zones of Karnataka state in rural India. North Karnataka is the most underdeveloped and remote zone of this program and did not have any ROP screening programs before the intervention of the KIDROP in 2011. Six government and eleven private neonatal centers in this zone were screened weekly. Specific neonatal guidelines for ROP were developed and introduced in these centers. They included awareness about risk factors, oxygen regulation protocols, use of pulse oxymetry, monitoring postnatal weight gain, nutritional best practices, and management of sepsis. The incidence and severity of ROP were compared before the guidelines were introduced (Jan 2011 to Dec 2012) and after the guidelines were introduced (July 2013 to June 2015). Results During this 4-year period, 4,167 infants were screened over 11,390 imaging sessions. The number of enrolled infants increased from 1,825 to 2,342 between the two periods (P<0.001). The overall incidence of any stage ROP reduced significantly from 26.8% to 22.4% (P<0.001). The incidence of treatment-requiring ROP reduced from 20.7% to 16% (P=0.06), and of the treated disease, aggressive posterior ROP reduced from 20.8% to 13.1% (P=0.23) following introduction of the guidelines. Discussion Rural neonatal centers in middle-income countries have a large, unscreened burden of ROP. Improving neonatal care in these centers can positively impact the incidence and severity of ROP even in a relatively short period. A combined approach of a robust ROP screening program and improved neonatal care practices is required to address the challenge. PMID:28539801

Full Text Available Individuals who were born very preterm (VPT; <33 gestational weeks are at risk of experiencing deficits in tasks involving executive function in childhood and beyond. In addition, the type and severity of neonatal brain injury associated with very preterm birth may exert differential effects on executive functioning by altering its neuroanatomical substrates. Here we addressed this question by investigating with functional magnetic resonance imaging (fMRI the haemodynamic response during executive-type processing using a phonological verbal fluency and a working memory task in VPT-born young adults who had experienced differing degrees of neonatal brain injury. 12 VPT individuals with a history of periventricular haemorrhage and ventricular dilatation (PVH+VD, 17 VPT individuals with a history of uncomplicated periventricular haemorrhage (UPVH, 13 VPT individuals with no history of neonatal brain injury and 17 controls received an MRI scan whilst completing a verbal fluency task with two cognitive loads ('easy' and 'hard' letters. Two groups of VPT individuals (PVH+VD; n = 10, UPVH; n = 8 performed an n-back task with three cognitive loads (1-, 2-, 3-back. Results demonstrated that VPT individuals displayed hyperactivation in frontal, temporal, and parietal cortices and in caudate nucleus, insula and thalamus compared to controls, as demands of the verbal fluency task increased, regardless of type of neonatal brain injury. On the other hand, during the n-back task and as working memory load increased, the PVH+VD group showed less engagement of the frontal cortex than the UPVH group. In conclusion, this study suggests that the functional neuroanatomy of different executive-type processes is altered following VPT birth and that neural activation associated with specific aspects of executive function (i.e., working memory may be particularly sensitive to the extent of neonatal brain injury.

The Tromsø Intervention Study on Preterms evaluates an early, sensitizing intervention given to parents of prematurely born children (birth-weight influence of the intervention on children's self-reported and parental proxy-reported quality of life (QoL) at children's age of nine. Participants were randomized to either intervention (PI, n = 72) or preterm control (PC, n = 74) in the neonatal care unit, while healthy term-born infants were recruited to a term reference group (TR, n = 75). The intervention was a modified version of the Mother-Infant Transaction Program, and comprised eight one-hour sessions during the last week before discharge and four home visits at 1, 2, 4 and 12 weeks post-discharge. The two control groups received care in accordance with written guidelines drawn up at the hospital. Participants and parents reported QoL independently on the Kinder Lebensqualität Fragebogen (KINDL) questionnaire. Differences between groups were analyzed by SPSS; Linear Mixed Models and parent-child agreement were analyzed and compared by intra-class correlations within each group. On average, children in all groups reported high levels of well-being. The PI children reported better physical well-being than the PC children (p = 0.002). In all other aspects of QoL both the PI and the PC children reported at similar levels as the term reference group. PI parents reported better emotional wellbeing (p = 0.05) and a higher level of contentment in school (p = 0.003) compared with PC parents. Parent-child agreement was significantly weaker in the PI group than in the PC group on dimensions such as emotional well-being and relationships with friends (p parents reported QoL similar to parents of terms on all aspects except the subscale self-esteem, while PC parents generally reported moderately lower QoL than TR parents. This early intervention appears to have generated long-lasting positive effects, improving perceived physical well

Retinopathy of prematurity (ROP) is a multifactorial disease with evidence of many associated risk factors. Erythropoietin has been reported to be associated with this disorder in a murine model, as well as in humans in some single-center reports. We reviewed the data from two large tertiary NICUs in Italy to test the hypothesis that the use of erythropoietin may be associated with the development of the most severe stages of ROP in extremely low birth weight (ELBW) neonates. Retrospective study by review of patient charts and eye examination index cards on infants with birth weight large tertiary NICUs in Northern Italy (Sant'Anna Hospital NICU in Torino, and Ca' Foncello Hospital Neonatology in Treviso) in the years 2005 to 2007. Standard protocol of administration of EPO in the two NICUs consisted of 250 UI/kg three times a week for 6-week courses (4-week in 1001-1500g infants). Univariate analysis was performed to assess whether the use of EPO was associated with severe (threshold) ROP. A control, multivariate statistical analysis was performed by entering into a logistic regression model a number of neonatal and perinatal variables that - in univariate analysis - had been associated with threshold ROP. During the study period, 211 ELBW infants were born at the two facilities and survived till discharge. Complete data were obtained for 197 of them. Threshold retinopathy of prematurity occurred in 26.9% (29 of 108) of ELBW infants who received erythropoietin therapy, as compared with 13.5% (12 of 89) of those who did not receive erythropoietin (OR 2.35; 95% CI 1.121-4.949; p=0.02 in univariate analysis, and p=0.04 at multivariate logistic regression after controlling for the following variables: birth weight, gestational age, days on supplemental oxygen, systemic fungal infection, vaginal delivery). Use of erythropoietin was not significantly associated with other major sequelae of prematurity (intraventricular hemorrhage, bronchopulmonary dysplasia, necrotizing

Full Text Available BACKGROUND AND OBJECTIVE: Approximately 80% of premature infants are diagnosed with icterus, most of whom are treated by phototherapy. Given the adverse effects of this treatment on neonates, minimizing the duration of phototherapy seems to be necessary. This study aimed to evaluate the effects of massage on the duration of phototherapy in premature infants admitted to neonatal intensive care units. METHODS: This clinical trial was performed on premature infants admitted to the neonatal intensive care unit of Qaem Hospital of Mashhad, Iran, in 2011. The infants were randomly divided into intervention (n=30 and control (n=30 groups. The infants of both groups were similar in terms of weight, age, and the level of bilirubin. The intervention group received massage therapy (including massage and passive movements of the body parts on a daily basis for three 15-minute courses at three consecutive hours for five days. The control group received the routine care and phototherapy. After the intervention, the two groups were compared in terms of duration of phototherapy and level of transcutaneous bilirubin. FINDINGS: The mean duration of phototherapy in the intervention and control groups was 80.8±61.58 and 112.8±75.45 hours, respectively. However, this difference was not statistically significant. On the fifth day of the intervention, the level of transcutaneous bilirubin was 9.7 and 8.1 mg/dl in the intervention and control groups, respectively, this difference was not significant as well. CONCLUSION: Massage can be used as an effective method alongside with phototherapy to minimize the duration of phototherapy for premature healthy infants in clinically stable conditions.

Using prospective longitudinal data from 198 very preterm and 70 full term children, this study characterised the memory and learning abilities of very preterm children at 7 years of age in both verbal and visual domains. The relationship between the extent of brain abnormalities on neonatal magnetic resonance imaging (MRI) and memory and learning outcomes at 7 years of age in very preterm children was also investigated. Neonatal MRI scans were qualitatively assessed for global, white-matter, cortical grey-matter, deep grey-matter, and cerebellar abnormalities. Very preterm children performed less well on measures of immediate memory, working memory, long-term memory, and learning compared with term born controls. Neonatal brain abnormalities, and in particular deep grey matter abnormality, were associated with poorer memory and learning performance at 7 years in very preterm children, especially global, white-matter, grey-matter and cerebellar abnormalities. Findings support the importance of cerebral neonatal pathology for predicting later memory and learning function. PMID:23805915

The main clinical outcomes were occurrence of any stage of ROP and in particular severe ROP. Perinatal variables considered were: birth weight, gestational age, gender, method of ventilation (nasal continuous airway pressure or intermittent mechanical ventilation, packed red blood cell and/or plasma transfusion, occurrence of sepsis, neonatal indirect hyperbilirubinemia, intraventricular hemorrhage, and patent ductus arteriosus. After obtaining informed consent from the parents, infants at risk were examined for ROP using indirect ophthalmoscopy, ie, RetCam II fundus photography.Results: The study included 152 infants of mean gestational age 31.02 weeks and mean birth weight 1.229 kg. Seventy-two cases (47.5% were male and 80 cases (52.5% were female. Of the cases screened, 100 (65.6% had no ROP, 52 had ROP of any stage (34.4%, and 27 (18% had stage 1, five (3.3% had stage 2, 17 (11.5% had stage 3, and three (1.6% had stage 4 disease. No infants had stage 5 ROP. Of all our cases with ROP, 15 (28.6% had prethreshold disease type 1 that required treatment, comprising 9.8% of all cases screened for ROP. Using stepwise logistic regression analysis, all risk factors studied were found to be significantly associated with the development of ROP, except for neonatal indirect hyperbilirubinemia. Severity of ROP was inversely proportional to birth weight and gestational age.Conclusion: ROP occurred in 34.4% of all infants screened in the neonatal intensive

We aimed to determine applicable guidelines for screening of retinopathy of prematurity (ROP), and evaluate the contribution of risk factors for severe ROP. A prospective cohort study of neonates with a gestational age (GA) < 34 weeks or birth weight < 2000g who were admitted to the Neonatal Intensive Care Unit (NICU) of a tertiary level hospital was conducted. The study group was classified into three groups according to eye examination findings as no ROP, mild ROP and severe ROP. Of the 700 neonates screened, the frequencies of ROP for any stage and severe ROP were 32.7% and 3.1%, respectively. Laser photocoagulation was needed in 9.6% of neonates with ROP. None of the neonates with a GA ≥ 31 weeks required treatment. Any ROP was detected in 199 (53.6%) of the babies < 32 weeks (n = 371), 22 (5.9%) of whom were treated with laser photocoagulation. Independent risk factors for severe ROP in babies < 32 weeks GA were birth weight, duration of mechanical ventilation and patent ductus arteriosus (PDA). This is the largest prospective cohort study including infants younger than 34 weeks GA from Turkey. Our data which belongs to the last 1-year period shows lower incidence of severe ROP when compared to previous reports from Turkey. According to our data, screening babies smaller than 32 weeks GA or 1500g birth weight seems reasonable. In the presence of long duration of mechanical ventilation and PDA, screening should be intensified.

,5% 2-5 consultas y 27,1% refieren 6 o más, 16,2% de las madres presentaron Dolencia Hipertensiva del Estado Gestacional (DHEG, y 51,3% tuvieran parto normal. Se concluye que la prematuridad fué elevada, representando importante causa de la morbimortalidad neonatal, como también acarretar complicaciones clínicas y obstétricas para la madre. La DHEG aún representa um risco para la gestación. És necesário que nuevos estúdios sobre la temática sean realizados para se conocer la verdadera magnitud del problema.This is a descriptive study that took place in a public maternity in Fortaleza Ce, with objective to characterize the prematureness among newly born (RN interned in the Unidade Neonatal due to the premature amniorrexe. It was analyzed 37 newborns along with their mothers. From the newborns it was analyzed: prematureness degree, Apgar and reanimation need; and from their mothers: gestational age, pre natal care, birth and gestational pathologies. It was found that 35,1% of the babies are premature and 29,7% had a 0-6 Agar during the first minute of life, needing reanimation. As for the gestational age, 35,1% presented membrane ruptures before the 37th week of birth, 5,4% did not go through pre natal care, 67,5% attended from 2 to 5 appointments and 27,1% attended to 6 or more, 16,2% of the mothers presented Gestational Specific Highblood Pressure Disease (GSHPD and 51,3% of the mothers went through normal delivery. It was concluded that the prematureness was high, being a main cause of newborn morbid/mortality and that it also brings clinical and obstetric complications for the mothers. The GSHPD still represents a risk to pregnancy. More studies on the subject are needed in order to acknowledged the real magnitude of the problem.

Pentraxin 3 (PTX3) is an acute phase reactant which has been used to detect intra-amniotic infections (IAI) in pregnancy, but the prognostic value of PTX3 concentrations on neonates has not been studied. We aimed to investigate the relationship between maternal PTX3-neonatal PTX3 concentrations and early neonatal outcome. The mothers diagnosed with preterm prelabor rupture of membranes (PPROM) (n = 28) and their preterm infants (n = 28) were included in the study. PTX3 concentrations were studied in plasma in the maternal peripheral blood and umbilical/peripheral vein in the neonates. The relationship between the mPTX3-nPTX3 concentrations and neonatal outcome were investigated using non-parametric tests and binary logistic regression analysis. The mean mPTX3 concentration was 10.35 ± 7.82 μg/L. Ten (35.7%) of all mothers were within the normal range and 18 (64.3%) in high percentile (≥ 97.5 percentile). There was no relation between mPTX3 concentrations and clinical or histologic chorioamnionitis, latency of PPROM, and early neonatal outcome. Mean nPTX3 concentrations was 9.18 ± 7.83 μg/L and high nPTX3 concentrations were detected in five (17.8%) neonates. nPTX3 concentrations were inversely correlated with gestational age and correlated with rate of intraventricular hemorrhage (IVH) and mortality. Neonates with high nPTX3 concentrations also have lowered APGAR scores, increased rate of respiratory distress syndrome, clinical sepsis, IVH, necrotizing enterocolitis and prolonged NICU stay. High PTX3 concentrations of the newborns are associated with some worsened early neonatal outcome including lower gestational age at delivery, increased rate of IVH and mortality. Maternal PTX3 concentrations are not an adequate marker in defining clinical or histologic chorioamnionitis and early neonatal outcome.
Conclusion: In VLBW infants born prior to 32 weeks' gestation, IVH is a risk factor for impaired development. Its effects on psychomotor development, but not mental development, are still apparent at 2 years of age.

We explored whether repeated dose of antenatal betamethasone and variation in intrauterine growth of prematurely born children predict temperament characteristics at the age of 2 years. The patients (n = 142) were prematurely born children (mean gestational age: 31.0 weeks; range: 24.6-35.0 weeks) who participated in a randomized and blinded trial testing the effects of a repeated dose of antenatal betamethasone in imminent preterm birth. Fetal growth was estimated as weight, length, and head circumference in SDs according to Finnish growth charts. Parents assessed their toddlers' temperament with 201 items of the Early Childhood Temperament Questionnaire (mean child corrected age: 2.1 years). No significant main effects of repeated betamethasone on toddler temperament existed. However, a significant interaction between study group and duration of exposure to betamethasone emerged; those exposed to a repeated dose for >24 hours before delivery were more impulsive. One-SD increases in weight, length, and head circumference at birth were associated with 0.14- to 0.19-SD lower levels of negative affectivity (fearfulness, anger proneness, and sadness); 1-SD increases in length, weight, and head circumference at birth were associated with 0.14- to 0.18-SD higher levels of effortful control (self-regulation). Repeated antenatal betamethasone did not induce alterations in toddler temperament. The results, however, suggest that a longer duration of exposure is associated with higher impulsivity scores. Regardless of betamethasone exposure, slower fetal growth exerted influences on temperament. Our findings indicate prenatal programming of psychological development and imply that more attention is needed to support the development of infants born at the lower end of the fetal growth distribution.

To compare mortality and neurodevelopmental outcomes of outborn and inborn preterm infants born at neurodevelopmental impairment (NDI), and overall NDI were compared between outborn and inborn infants at 18-21 months of age, corrected for prematurity. Of 2951 eligible infants, 473 (16%) were outborn. Mean birth weight (940 ± 278 g vs 897 + 237 g), rates of treatment with antenatal steroids (53.9% vs 92.9%), birth weight small for gestational age (5.3% vs 9.4%), and maternal college education (43.7% vs 53.9%) differed between outborn and inborn infants, respectively (all P values neurodevelopmental impairment were significantly higher in outborn compared with inborn infants admitted to Canadian NICUs. Adverse outcomes were mainly attributed to increased mortality and cerebral palsy in outborn neonates. Copyright © 2017 Elsevier Inc. All rights reserved.

The link between deformational plagiocephaly and psychomotor development is a recurrent question in medical publications. Main publications concentrate on term infants, but there is a lack of data on the impact of deformational plagiocephaly on the long-term neurodevelopment of premature infants. We attempted to establish a possible relation between deformational plagiocephaly during the 1st year of life and the psychomotor score at 4 years in prematurely born infants. Other risk factors potentially impacting the psychomotor score were also studied. A retrospective study of the files of the children followed by the "Naître et Devenir Région PACA Ouest Corse Sud" healthcare network and included in the database allowed us to select a cohort of 594 infants born prematurely at under 33 weeks of gestational age. These children were developmentally evaluated during the 1st year of life and at 4 years or age using the "EVAL Mater" test. The "Naître et Devenir" network is following up infants born prematurely at under 33 weeks of gestation in the West Provence Alpes Côte d'Azur and South Corsica region, from discharge to 7 years. A group of 170 specially trained pediatricians follow these infants developmentally at term, 3, 6, 9, 12, 18, and 24 months of corrected age and 3, 4 5, 6, and 7 years. Data are collected in a specially designed database. There was no significant link between deformational plagiocephaly during the 1st year of life and a pathological psychomotor score at age 4, but some risk factors were demonstrated: male gender, birth at under 28 weeks of gestational age, weight at birth under 1000g, having a Latal and Ferriero neuromotor score equal to or greater than 2 at 3 months of corrected age, and to a lesser extent having a prescription for physiotherapy during the 1st year. The research on deformational plagiocephaly in the full-term infant suggests a relation between deformational plagiocephaly and developmental delay predominantly

Full Text Available Little is known about motor development in late preterm born infants. Our objective was to determine long-term outcome of motor skills of infants born between 32 and 34 weeks. All infants were assessed at corrected ages of 3 and 9 months, using the Alberta Infant Motor Scale. At corrected ages of 4 years, the Movement Assessment Battery for Children was done. Seventy infants were seen at 4 years of age (median of 3 assessments per infant. Abnormal assessment at 3 or 9 months of age resulted in normal outcome in almost 80% at 4 years. On the other hand, a normal outcome in the first year of life resulted in an abnormal outcome at 4 years in 10% of the infants. Our results suggest that long-term followup of these late preterm born infants is necessary, as the assessments in the first year do not predict the long-term outcome.

To evaluate adherence to a delayed cord clamping protocol for preterm births in the first 2 years after its introduction, perform a quality improvement assessment, and determine neonatal outcomes associated with protocol implementation and adherence. This is a retrospective cohort study of women delivering singleton neonates at 23-32 weeks of gestation in the 2 years before (preprotocol) and 2 years after (postprotocol) introduction of a 30-second delayed cord clamping protocol at a large-volume academic center. This policy was communicated to obstetric and pediatric health care providers and nurses and reinforced with intermittent educational reviews. Barriers to receiving delayed cord clamping were assessed using χ tests and multivariable logistic regression. Neonatal outcomes then were compared between all neonates in the preprotocol period and all neonates in the postprotocol period and between all neonates in the preprotocol period and neonates receiving delayed cord clamping in the postprotocol period using multivariable linear and logistic regression analyses. Of the 427 eligible neonates, 187 were born postprotocol. Of these, 53.5% (n=100) neonates received delayed cord clamping according to the protocol. The rate of delayed cord clamping preprotocol was 0%. Protocol uptake and frequency of delayed cord clamping increased over the 2 years after its introduction. In the postprotocol period, cesarean delivery was the only factor independently associated with failing to receive delayed cord clamping (adjusted odds ratio [OR] 0.49, 95% confidence interval [CI] 0.25-0.96). In comparison with the preprotocol period, those who received delayed cord clamping in the postprotocol period had significantly higher birth hematocrit (β=2.46, P=.007) and fewer blood transfusions in the first week of life (adjusted OR 0.49, 95% CI 0.25-0.96). After introduction of an institutional delayed cord clamping protocol followed by continued health care provider education and
Full Text Available Introduction: One of the common problems in neonatal period is jaundice that occurs in the first week of birth in 60% of term and 80% of preterm neonates. In preterm newborn hyperbilirubinaemia is higher, persistent, longer, and more likely to be associated with neurological injury than term neonates. The purpose of this study was to determine Prophylactic effect of zinc sulphate on hyperbilirubinemia in premature very low birth weight neonates. Method and Material: Sixty Newborns who admitted in our NICU which had inclusion criteria were eligible in this trial. Included neonates were randomly placed in two groups (case and control and before intervention the total serum bilirubin (TSB was measured at second day. The participant received either 20 mg of zinc sulfate or placebo through NG-tube divided in two doses till day seven of age. Then total and indirect bilirubin was measured at 3ed, 5th and 7th day of life. If any of newborns in duration of hospitalization develop clinical jaundice, after assessment of bilirubin, need for phototherapy was evaluated based on phototherapy and exchange schedule as described by the American Academy of Pediatrics guidelines. The termination point of phototherapy was defined as a bilirubin level less than 50 percent of starting point. After gathering Data, they were analyzed using SPSS software (version 11.5 and T-test, Chi-square and repeated measurement tests. Results: Seventy eight patients enrolled in this trial that 18 cases were excluded and the remaining cases divided into two equal groups (N=30 in each group. Demographic condition was similar in two groups. There were no different between two groups in decreasing total serum bilirubin and duration of phototherapy. Conclusion: This study showed that zinc sulfate has no preventing effective in hyperbilirubinemia in preterm very low birth weight neonates. It has also no effect on duration of phototherapy.

Infants born near the limit of viability are at high risk for death or adverse neurodevelopmental outcomes. It is unclear whether these outcomes have improved over the past 15 years. To determine if death and neurodevelopmental impairment have declined over the past 15 years in infants born at 22 to 24 weeks' gestation. Retrospective cohort study. We identified infants born at 22 to 24 weeks' gestation in our center in two epochs: 1998-2004 (Epoch 1) and 2005-2011 (Epoch 2). The primary outcome, death or neurodevelopmental impairment, was evaluated at 17-25 months' corrected gestational age with neurologic exams and Bayley Scales of Infant Development. Perinatal characteristics, major morbidities, and outcomes were compared between epochs. Birth weight and gestational age were similar between 170 infants in Epoch 1 and 187 infants in Epoch 2. Mortality was significantly lower in Epoch 2, 55% vs. 42% (p=0.02). Among surviving infants, late-onset sepsis (pNeurodevelopmental impairment among surviving infants declined from 68% in Epoch 1 to 47% in Epoch 2, p=0.02. Odds of death or NDI were significantly lower in Epoch 2 vs. Epoch 1, OR=0.31 (95% confidence interval; 0.16, 0.58). Risk of death or neurodevelopmental impairment decreased over time in infants born at 22 to 24 weeks' gestation. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Close to one in ten individuals worldwide is born preterm, and it is important to understand patterns of long-term health and mortality in this group. This study assesses the relationship between gestational age at birth and early adult mortality both in a nationwide population and within sibships. The study adds to existing knowledge by addressing selected causes of death and by assessing the role of genetic and environmental factors shared by siblings.Study population was all Norwegian men and women born from 1967 to 1997 followed using nation-wide registry linkage for mortality through 2011 when they were between 15 and 45 years of age. Analyses were performed within maternal sibships to reduce variation in unobserved genetic and environmental factors shared by siblings. Specific outcomes were all-cause mortality and mortality from cardiovascular diseases, cancer and external causes including accidents, suicides and drug abuse/overdoses.Compared with a sibling born in week 37-41, preterm siblings born before 34 weeks gestation had 50% increased mortality from all causes (adjusted Hazard Ratio (aHR 1.54, 95% confidence interval (CI 1.17, 2.03. The corresponding estimate for the entire population was 1.27 (95% CI 1.09, 1.47. The majority of deaths (65% were from external causes and the corresponding risk estimates for these deaths were 1.52 (95% CI 1.08, 2.14 in the sibships and 1.20 (95% CI 1.01, 1.43 in the population.Preterm birth before week 34 was associated with increased mortality between 15 and 45 years of age. The results suggest that increased premature adult mortality in this group is related to external causes of death and that the increased risks are unlikely to be explained by factors shared by siblings.

To describe fathers' experiences of starting family life with an infant delivered prematurely out of necessity of saving the mother's and infant's lives due to the mother's severe preeclampsia. A descriptive, qualitative design was used. Six fathers were interviewed twice: from 6 to 24 days and from 4 to 22 weeks after delivery. Data were transcribed verbatim and analyzed using a reflective lifeworld research approach. The essence of the fathers' experiences of establishing a family with a seriously ill mother and a premature infant can be described as a process of becoming a family through reflection on life and death in a context of separation. The essence specifically comprised the following constituents: (1) starting fatherhood facing existential issues, (2) connecting the family, (3) becoming familiar with your infant, and (4) becoming a father in a public area. The fathers were able to develop their relationship to their infants; this emphasizes the importance of the fathers being able to spend their time in the NICU. The privacy of the fathers were more or less challenged, health professionals should be aware of individualize their approach to the fathers. The study reveals that family life started with separation. Health professionals should try to ensure that the family should be together. Mutual guidelines between the wards that treats mother and child should be implemented. When new mother and child-centers are planned a family friendly environment should be prioritized.

Full Text Available Background The most common cause of admission to neonatal intensive care units (NICU is respiratory distress syndrome. One of the respiratory assistance methods is using nasal continuous positive airway pressure (CPAP. Regarding the importance of pain control which is one of the major priorities in neonatal nursing care, this study aimed to evaluate the effect of body position on pain due to nasal CPAP in premature neonates. Materials and Methods In this cross-over clinical trial, 50 premature neonates who were receiving nasal CPAP admitted to the NICU of Imam Reza Hospital, Kermanshah, Iran, were included. The neonates were randomly placed at three body positions (fetal, supine, and prone positions. Pain was measured by Astrid Lindgren Children’s Hospital Pain Scale Neonates (ALPS-Neo pain assessment scale. The collected data were analyzed using the SPSS software (Version 22.0. Results Significant difference existed regarding pain of nasal CPAP among body positions (p< 0.001. Mean (SD pain was 5.15 (0.822 in fetal position, 6.260 (0.747 in prone position and 7.326 (0.792 in supine position. Conclusion Body positioning in premature neonates under nasal CPAP in NICU can be effective as a non-pharmacologic method in alleviating pain due to nasal CPAP. Among the studied positions, the lowest pain score was seen in fetal position.

The safety of surgical closure of patent ductus arteriosus (PDA) in very low birth weight premature neonates has been questioned because of associated morbidities. However, these studies are vulnerable to significant bias as surgical ligation has historically been utilized as "rescue" therapy. The objective of this study was to review our institutions' outcomes of surgical PDA ligation. All neonates with operative weight of ≤1.00 kg undergoing surgical PDA ligation from 2003 to 2015 were analyzed. Records were queried to identify surgical complications, perioperative morbidity, and mortality. Outcomes included pre- and postoperative ventilator requirements, pre- and postoperative inotropic support, acute kidney injury, surgical complications, and 30-day mortality. One hundred sixty-six preterm neonates underwent surgical ligation. One hundred twenty-one (70.3%) had failed indomethacin closure. One hundred sixty-four (98.8%) patients required mechanical ventilation prior to surgery. At 17 postoperative days, freedom from the ventilator reached 50%. Of 109 (66.4%) patients requiring prolonged preoperative inotropic support, 59 (54.1%) were liberated from inotropes by postoperative day 1. Surgical morbidity was encountered in four neonates (2.4%): two (1.2%) patients had a postoperative pneumothorax requiring tube thoracostomy, one (0.6%) patient had a recurrent laryngeal nerve injury, and one (0.6%) patient had significant intraoperative bleeding. The 30-day all-cause mortality was 1.8% (n = 3); no deaths occurred intraoperatively. In this retrospective investigation, surgical PDA closure was associated with low 30-day mortality and minimal morbidity and resulted in rapid discontinuation of inotropic support and weaning from mechanical ventilation. Given the safety of this intervention, surgical PDA ligation merits consideration in the management strategy of the preterm neonate with a PDA.

Introduction: Improved survival of very low birth weight (VLBW) premature infants requires urgent intensive care, professional nursing and medical care. On the other hand, long hospital stay period imposes emotional and economic burdens on the family and society. Therefore, it is necessary to clarify the most important factors affecting their hospitalization duration to lessen unwanted outcomes of premature birth and to eliminate or relieve the problems.

Full Text Available This study reported our experience of bedside patent ductus arteriosus (PDA ligation for prematurity in the neonatal intensive care unit (NICU. Between April 1992 and March 2006, 41 very-low-birth-weight premature infants underwent PDA ligation in the NICU. There were 18 male and 23 female infants. The mean gestational age and birth weight were 26.9 weeks and 900.9 g, respectively. Preoperatively, 25 infants were ventilator-dependent. After operation, there were five deaths caused by complications of prematurity. Surgical complications occurred in four and all recovered well after treatment. Twenty preoperatively intubated babies survived and were extubated at 21.6 ± 12.7 days postoperatively. In conclusion, bedside PDA ligation in the NICU is safe and effective. It can avoid transportation of critically ill, very small infants. We suggest surgical closure as the primary treatment in very-low-birth-weight infants who are ventilator-dependent to avoid the possible complications of indomethacin and prolonged intubation.

Does neonatal outcome including congenital malformations in children born after ICSI with epididymal and testicular sperm [testicular sperm extraction (TESE)/percutaneous epididymal sperm aspiration (PESA)/testicular sperm aspiration (TESA) (TPT)] differ from neonatal outcome in children born after ICSI with ejaculated sperm, IVF and natural conception (NC)? Children born after TPT have similar neonatal outcome, including total malformation rates, as have children born after ICSI and IVF with ejaculated sperm. Testing for variance over the four groups may indicate smaller differences in specific malformation rates with TPT as the highest risk group. Regarding neonatal outcome as well as congenital malformations in children born after TPT, studies are few, with limited sample size, heterogeneous and often performed without relevant control groups. Population-based cohort study including all Danish children born after TPT and fresh embryo transfer in Denmark from 1995 to 2009. Children born after transfer of frozen-thawed embryos were excluded. Control groups of children conceived by ICSI with ejaculated sperm, IVF and NC were identified by cross-linkage of the Danish IVF Register, Medical Birth Register (MBR) and National Hospital Discharge Register (HDR). The study group consisted of 466 children born after TPT, while the control groups consisted of 8967 (ICSI with ejaculated sperm), 17 592 (IVF) and 63 854 (NC) children. Neonatal outcomes and congenital malformations were analysed for singletons and twins separately. Risk estimates for low birthweight (LBW, congenital malformations in the TPT group was 7.7% and did not differ significantly from any of the control groups. However, singleton TPT boys showed an increased rate of cardiac malformations (3.6%) compared with singleton boys after IVF (1.4%; P = 0.04) and NC (1.1%; P = 0.02). Considering the level of male infertility as a continuum over the four groups, tests for variance in the rate of cardiac

Chest radiography has been the traditional method of diagnostic evaluation of patients of hyaline membrane disease (HMD). Lung sonography (USG) has been lately explored as an alternative modality. To explore the application of transabdominal USG of lung bases (TASL) in the evaluation of HMD in premature neonates with respiratory distress soon after birth. Tertiary care institutional setup. Study duration–18 months. Follow-up–variable, up to 1 month. Prospective descriptive study. Eighty-eight consecutive patients admitted in the neonatal intensive care unit (NICU) with gestational age <32 weeks having respiratory distress within 6 h of birth were enrolled. The diagnosis of HMD was made if the patient had negative gastric shake test and/or suggestive chest radiograph. TASL was performed in all patients within the first 24 h of life and biweekly subsequently. USG was interpreted as normal, HMD pattern, or broncho-pulmonary dysplasia (BPD) pattern. Biweekly follow-up was done for patients showing HMD till normalization of the sonographic HMD pattern, development of the sonographic BPD pattern, or death/discharge of the neonate from the hospital. TASL showed 85.7% sensitivity, 75% specificity, 88.88% positive predictive value, and 69.2% negative predictive value for the diagnosis of HMD. The abnormal sonographic findings on day 14 had 94.1% accuracy for prediction of eventual occurrence of clinical BPD. TASL is complementary to chest radiograph in the diagnosis of HMD. It is also useful for the early prediction of BPD with the potential of reducing the cumulative radiation dose to these neonates

To describe the perinatal and infant and early childhood morbidity associated with preterm premature rupture of membranes (PROM) in a cohort of twin pregnancies evaluated prospectively with neonatal follow-up to 2 years of age. This was a secondary analysis of a randomized controlled trial of magnesium sulfate for prevention of cerebral palsy. Inclusion criteria were twin gestation with preterm PROM diagnosed between 24 0/7 and 31 6/7 weeks of gestation and planned expectant management. Latency (time from membrane rupture to delivery) and perinatal outcomes were evaluated by gestational age at membrane rupture. Long-term neonatal outcomes were also analyzed. Among 151 women who met inclusion criteria, the median gestational age at preterm PROM was 28.1 weeks (range 24.1-31.6 weeks). Approximately one-third of women achieved a latency of at least 1 week. Gestational age at preterm PROM (odds ratio [OR] 0.75, 95% confidence interval [CI] 0.63-0.90 for each week after 24 weeks of gestation) and cervical dilation at admission (OR 0.66, 95% CI 0.49-0.90 for each centimeter of dilation) were inversely associated with a latency period of at least 1 week. There were no stillbirths (95% CI 0-1%), but the rate of neonatal mortality was 90 per 1,000 newborns (95% CI 57-112) with a 7.3% cerebral palsy rate among survivors (95% CI 4.4-10.3%). In twin pregnancies, preterm PROM from 24 to 31 weeks of gestation is associated with a neonatal mortality rate of 9.0% and an overall cerebral palsy rate of 7.3%. A longer latency period is associated with less advanced cervical dilation and later gestational age at PROM. LEVEL OF EVIEDENCE: II.

Low birthweight infants have a reduced number of nephrons and are at high risk of chronic kidney disease. Preterm birth and/or intrauterine growth restriction (IUGR) may also affect peritubular capillary development, as has been shown in other organs. We report two patients with a history of preterm birth and extremely low birthweight who showed polycythemia and renal capillary rarefaction. Patient 1 and 2, born at 25 weeks of gestation with a birthweight of 728 and 466 g, showed mild proteinuria at age 8 and 6 years, respectively. In addition to increasing proteinuria, hemoglobin levels became elevated towards adolescence and their serum erythropoietin (EPO) was high despite polycythemia. Light microscopic examination of renal biopsy specimens showed glomerular hypertrophy, focal segmental glomerulosclerosis, and only mild tubulointerstitial fibrosis. A decrease in the immunohistochemical staining of CD31 and CD34 endothelial cells in renal biopsy specimens was consistent with peritubular capillary rarefaction. Since kidney function was almost normal and fibrosis was not severe, we consider that the capillary rarefaction and polycythemia associated with elevated EPO levels were largely attributable to preterm birth and/or IUGR.

To assess the predictors of outcome in terms of length of stay in the neonatal intensive care unit (NICU) and survival of neonates from women with preterm premature rupture of membranes (PPROM). A population-based retrospective study including 331 singleton pregnant women with PPROM at 24-34 gestational weeks between January 2013 and December 2015 was conducted. Gestational age at delivery, birth weight, route of delivery, newborn gender, maternal age, oligohydramnios, premature retinopathy (ROP), necrotising enterocolitis (NEC), sepsis, fetal growth retardation (FGR), intracranial hemorrhagia (ICH), bronchopulmonary dysplasia (BPD), respiratory distress syndrome (RDS), primary pulmonary hypertension (PPH), congenital cardiac disease (CCD), patent ductus arteriosus (PDA), use of cortisol (betamethasone) and maternal complications including gestational diabetes, preeclampsia and chorioamnionitis were used to predict neonatal outcomes in terms of length of stay in the NICU and survival. In linear regression analyses, birth weight, ROP, CCD, BPD, PDA, NEC and preeclampsia were significant confounders for length of stay in the NICU. Among them, birth weight was the most powerful confounder for prolongation of the NICU stay (t: -6.43; p Prematurity-related complications are the most important problems for which precautions should be taken. Therefore, premature deliveries should be avoided to prevent infection and to prolong the latent period in cases of PPROM in order to decrease prematurity-related outcomes.

Spirituality is part of the basic needs of all humans, yet often undervalued by health professionals. Less is known about the spiritual needs of mothers of preterm or sick new born children. Identify unmet psychosocial and spiritual needs of these mothers, and to relate these needs to their perceived stress and impairments of life concerns. Anonymous cross-sectional survey with standardized instruments (e.g., Spiritual Needs Questionnaire) among 125 mothers of two paediatric departments in Germany. Mothers felt supported by their partner and hospital staff, and hospital staff assured 82% of them that they must not worry about their child's prognosis. They nevertheless did have specific unmet spiritual needs. Religious Needs and Existentialistic Needs scored lowest, while Giving/Generativity Needs were of moderate and Inner Peace Needs of strongest relevance. With respect to the expected diagnosis and prognosis of their child, there were no significant differences for their secular spiritual needs scores, but significant differences for Religious Needs which scored highest in mothers with children having an unclear prognosis (F=8.6; p=.004). Particularly Inner Peace Needs correlated with their stress perception (r=.34), impairments of life concerns (r=.25) and grief (r=.23). Mothers of sick born/premature children felt supported by the hospital team and their partner, but nevertheless experienced stress and daily life impairments, and particularly have unmet Inner Peace Needs. Addressing mothers' specific needs may help support them in their struggle with their difficult situation avoiding fears and insecurity and thus facilitating positive bonding to their child.

Comparing outcomes at different neonatal intensive care units (NICUs) requires adjustment for intrinsic risk. The Clinical Risk Index for Babies (CRIB) is a widely used risk model, but it has been criticized for being affected by therapeutic decisions. The Prematurity Risk Evaluation Measure (PREM) is not supposed to be prone to treatment bias, but has not yet been validated. We aimed to validate the PREM, compare its accuracy to that of the original and modified versions of the CRIB and CRIB-II, and examine the congruence of risk categorization.

The objective of this study is to assess the relationship between brain volumes at term equivalent age and neuropsychological functions at 5 years of age in very low birth weight (VLBW) children, and to compare the results from a neuropsychological assessment and a parental questionnaire at 5 years of age. The study group included a regional cohort of 97 VLBW children and a control group of 161 children born at term. At term equivalent age, brain magnetic resonance imaging (MRI) was performed on the VLBW children, and analysed for total and regional brain volumes. At 5 years of age, a psychologist assessed the neuropsychological performance with NEPSY II, and parents completed the Five to fifteen (FTF) questionnaire on development and behaviour. The results of the control group were used to give the age-specific reference values. No significant associations were found between the brain volumes and the NEPSY II domains. As for the FTF, significant associations were found between a smaller total brain tissue volume and poorer executive functions, between a smaller cerebellar volume and both poorer executive functions and motor skills, and, surprisingly, between a larger volume of brainstem and poorer language functions. Even after adjustment for total brain tissue volume, the two associations between the cerebellar volume and the FTF domains remained borderline significant (P = 0.05). The NEPSY II domains Executive Functioning, Language and Motor Skills were significantly associated with the corresponding FTF domains. In conclusion, altered brain volumes at term equivalent age appear to affect development still at 5 years of age. The FTF seems to be a good instrument when used in combination with other neuropsychological assessment.

Full Text Available Abstract Background Chronic lung disease (CLD in the preterm newborn is associated with inflammation and fibrosis. Platelet-derived growth factor-BB (PDGF-BB, a potent chemotactic growth factor, may mediate the fibrotic component of CLD. The objectives of this study were to determine if tracheal aspirate (TA concentrations of PDGF-BB increase the first 2 weeks of life in premature neonates undergoing mechanical ventilation for respiratory distress syndrome (RDS, its relationship to the development of CLD, pulmonary hemorrhage (PH and its relationship to airway colonization with Ureaplasma urealyticum (Uu. Methods Infants with a birth weight less than 1500 grams who required mechanical ventilation for RDS were enrolled into this study with parental consent. Tracheal aspirates were collected daily during clinically indicated suctioning. Uu cultures were performed on TA collected in the first week of life. TA supernatants were assayed for PDGF-BB and secretory component of IgA concentrations using ELISA techniques. Results Fifty premature neonates were enrolled into the study. Twenty-eight infants were oxygen dependent at 28 days of life and 16 infants were oxygen dependent at 36 weeks postconceptual age. PDGF-BB concentrations peaked between 4 and 6 days of life. Maximum PDGF-BB concentrations were significantly higher in infants who developed CLD or died from respiratory failure. PH was associated with increased risk of CLD and was associated with higher PDGF-BB concentrations. There was no correlation between maximum PDGF-BB concentrations and Uu isolation from the airway. Conclusions PDGF-BB concentrations increase in TAs of infants who undergo mechanical ventilation for RDS during the first 2 weeks of life and maximal concentrations are greater in those infants who subsequently develop CLD. Elevation in lung PDGF-BB may play a role in the development of CLD.

To investigate neonatal outcomes and congenital malformations in children born after in vitro fertilization (IVF) and vitrified embryo transfer cycles using human menopausal gonadotrophin and medroxyprogesterone acetate (hMG + MPA) treatment. We performed a retrospective cohort study including 4596 live born babies. During January 2014-June 2016, children born after either hMG + MPA treatment, gonadotropin releasing hormone agonist short protocol, or mild ovarian stimulation were included. The main outcome measures were neonatal outcomes and congenital malformations. Neonatal outcomes both for singletons and twins such as mean birth weight and length, gestational age, the frequency of preterm birth were comparable between groups. Rate of stillbirth and perinatal death were also similar. No significant differences were found in the overall incidence of congenital malformations between the three groups. Multivariable logistic regression indicated that hMG + MPA regimen did not significantly increase the risk of congenital malformations compared with short protocol and mild ovarian stimulation, with adjusted odds ratio of 1.22 [95% confidence interval (CI) 0.61-2.44] and 1.38 (CI 0.65-2.93), respectively, after adjusting for confounding factors. Our data suggested that compared with conventional ovarian stimulations, hMG + MPA treatment neither compromised neonatal outcomes of IVF newborns, nor did increase the prevalence of congenital malformations.

Retinopathy of prematurity (ROP) is a significant cause of childhood blindness. The aim of this study is to determine the feasibility of remifentanil analgesia during laser treatment of ROP performed in the neonatal intensive care unit (NICU). Remifentanil was infused continuously during the procedure starting with a dose of 0.2 µg/kg/min and increased gradually to 0.6 µg/kg/min to provide an adequate level of analgesia. We enrolled 64 infants. Remifentanil was infused continuously at a mean rate of 0.4 ± 0.1 μg/kg/min. No major adverse effects were observed except in two patients with reversible bradycardia and hypotension. Premature infant pain profile (PIPP) scores revealed no pain. Patients with bronchopulmonary dysplasia had similar remifentanil dosage, intubation duration, and extubation time. Remifentanil analgesia for ROP treatment performed in the NICU by pediatricians is a safe and effective modality. This modality offers a practical solution in hospitals without readily available pediatric anesthetists. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Cleansing, moisturizing, and protecting neonatal skin is important, but literature evaluating specific product lines is limited. The purpose of this study was to measure the influence of a skin care product line on overall skin condition, perineal erythema, and pain when applied to neonates in a neonatal intensive care unit (NICU). This was an open label, descriptive study. Comparisons were made between measurements taken at the beginning of the study to those at the end, on the same subjects. The study was conducted in a 41-bed NICU at Driscoll Children's Hospital in Corpus Christi, Texas, that serves 31 counties in the region. This NICU treats children needing level 2 and 3 care, with a 1:1 or 2:1 nurse staffing ratio. This is not a birthing center; patients come from other community hospitals. Twenty-nine neonates participated in the study; their average body weight was 1.39 kg (3.06 lb) and their average gestation was 31.7 weeks. A skin care product line was introduced into a neonatal intensive care unit for 14 days. The products included 2 cleansers, 2 moisturizers, and a skin protectant with zinc oxide. Three outcome measures were tracked: Neonatal Skin Condition Score (NSCS), Skin Erythema Scale (SES), and pain. Nurses were also given a product evaluation survey. Descriptive statistics were used to report percentages and trends. Paired t tests were used to compare the mean NSCS, SES, and pain scores from the first 2 days a subject was in the study to the mean of the scores from the last 2 days they were in the study. Subjects experienced approximately 1774 exposures to individual products during data collection. No differences were found in pain scores (P = .132), SES score (P = .059), or NSCS (P = .603) when mean values were compared at the beginning and end of the study. Analysis of the product evaluation survey for questions on cleaning, moisturizing, and reducing discomfort found that more than 90% of nurses ranked the new products as better than or

An in vitro study was carried out to determine the anti-Xa activity of heparin in binary parenteral nutrition (BPN) admixtures for premature neonates in our neonatal intensive care unit (NICU) after a 24-hour infusion, as well as to assess drug interaction with a 50% glucose solution. Two types of bags were prepared: (1) BPN admixtures (composition defined in the NICU) including sodium heparin at 77 UI/mL and (2) bags containing only G50% with sodium heparin at 193 UI/mL. The anti-Xa activity of heparin was measured in bags at T0, after the 24-hour infusion and in eluates at the outlet of the infusion line after 24hours, using a validated chromogenic anti-Xa method. Comparisons of the mean concentration observed with the theoretical value for anti-Xa activity were performed with the Student t-test. Mean values of anti-Xa activity do not differ significantly from the values expected for all conditions. We found a slight variation in anti-Xa activity when infused over 24hours for both types of bags, with and without in-line filtration, showing that heparin remains stable during this infusion period in both BPN admixtures and G50%.

Full Text Available This study investigated the incidence of retinopathy of prematurity (ROP and its risk factors in a tertiary referral hospital in Taiwan to evaluate the applicability of the ROP screening guidelines published by the American Academy of Pediatrics, American Academy of Ophthalmology, and American Association for Pediatric Ophthalmology and Strabismus in 2006 (2006 guidelines. A pediatric ophthalmologist applied the 2006 guidelines to screen for ROP and to treat with laser photocoagulation in each case. We retrieved all records of premature infants referred for ROP screening at the hospital during 2004 to 2008. Univariate logistic regression analysis was applied firstly to identify factors correlating with stage 3 ROP or with laser treatment, and then those significant (p < 0.05 risk factors were analyzed by multivariate logistic regression. In the 138 male and 118 female premature infants in this study, mean gestation age was 30.8 ± 2.8 weeks, and mean birth weight was 1464.7 ± 434.2 g. The percentage of infants with ROP in at least one eye was 38.7%. Thirty two (12.5% had ROP stage 3 or higher in at least one eye. Multivariate logistic regression analysis showed that the best predictors of type 1 pre-threshold ROP (requiring laser treatment were young gestational age, low birth weight and male gender. As medical care of extremely premature infants improves, timely identification and treatment of conditions such as ROP are essential. Although the incidence of ROP in this institute was comparable to that in developing countries and higher than that in developed countries, the 2006 guidelines originally developed for a United States population were still applicable. However, the 2006 guidelines should be modified for a Taiwan population by considering gender.

Full Text Available We present a case of a 26-week premature newborn with an immature intrapericardial teratoma. The patient was transferred from an outside hospital for management of a large mediastinal mass causing respiratory insufficiency. The newborn was supported with the help of a large interdisciplinary team until day of life 22 when he underwent surgical excision. On follow up the infant is doing very well and is one of the youngest survivors to date.

Full Text Available During more than 70 years retinopathy of premature infants (previously — retrolental retinopathy has been one of the main problems in neonatology practice. This is caused firstly by the high risk of blindness development and visual disability and secondly — by the steady increase of health care allowing infants previously believed to be incurable to survive. Success in prevention of development of severe forms of this disorder nowadays depends not only on knowledge and experience of pediatric ophthalmologists. To the great extent it is associated to efforts and awareness of all levels of medical care participating in management of premature infants: from maternity hospitals, including departments of intensity care and neonatology, to out-patients clinics. According to the review of modern literature the article contains the main data on etiology, risk factors, pathogenesis, classification, clinical manifestation, diagnostics, prophylaxis and treatment of retinopathy of premature infants. The author also noted the tendencies to reveal the disease in the modern history of the Russian Federation. It is important to say, that urgency of this problem in the Russian Federation has significantly raised during the last years due to switch since the 1st January 2012 to the live birth criteria recommended by the World Health Organization.

Criteria for screening preterm infants for retinopathy of prematurity vary around the world. We aimed to analyse the efficacy of alternative screening criteria. We collected retrospective data at a tertiary level neonatal nursery. Our participants were 1007 babies, born between 1997 and 2011, at prematurity. We determined whether disease would be detected using an alternative Australian screening model (gestational age prematurity is our main outcome. Using several of the alternative criteria, two neonates with clinically significant retinopathy of prematurity, one of whom required laser treatment to preserve sight, would not have been screened, and their disease may have gone undetected. Use of prematurity may risk clinically significant cases being missed and others may screen babies unnecessarily. Alternative criteria should be considered and '<30 weeks gestational age and/or <1500 g birth weight' appears a viable option. © 2015 Royal Australian and New Zealand College of Ophthalmologists.
Introduction Jaundice is the yellowish pigmentation of the skin, sclera, and mucous membranes resulting from bilirubin deposition. Children born to mothers with HIV are more likely to be born premature, with low birth weight, and to become septic—all risk factors for neonatal jaundice. Further, there has been a change in ...
Radioimmunological determination of dehydroepiandrosterone sulfate in premature, mature and deficient born children as a parameter in the determination of the functional condition of the fetal adrenal cortex
The starting point of this work was the question of a correlation between serum concentration of dehydroepiandrosterone sulfate (DS) and gestation age. It was shown that after the sixth day of life, a negative correlation existed between the DS concentration in the serum of neonates and their gestation age. With non-stressed neonates DS can be used as a parameter of maturity. Vaginal birth and severe illness of premature, respectively newborn children cause a massive stimulation of DS secretion through the fetal zone of the adrenal cortex. Between the DS concentrations and the prolactin levels no correlation could be proven, so that there can be no discussion of prolactin as an alternative stimulator on the fetal zone of the adrenal cortex. The DS values presented in this work for premature and mature neonates of varying gestation age can be used as reference values by pediatric endocrinologists for the evaluation of a newborn with the suspect diagnosis of an adrenogenital syndrome or an adrenal insufficiency. The DS-radioimmunoassay is a practicable method for newborns because of its simplicity, quickness, and demand for only small amounts of serum and it is sufficiently specific and provides a good statement about the functional condition of the adrenal gland of newborns.

This historical cohort study aimed to assess the relationship between antenatal maternal C-reactive protein (CRP) level and neonatal outcome preterm premature rupture of membranes (PPROM). We reviewed the records of 70 singleton pregnancies with PPROM between 24 and 34 weeks. Maternal CRP levels of neonates with respiratory distress syndrome, neonatal sepsis, grade 3-4 intraventricular haemorrhage and stage 2-3 necrotizing enterocolitis, perinatal mortality were compared with those without these complications. Administration of corticosteroid, tocolysis for two days and prophylactic antibiotics (intravenous ampicillin/sulbactam, and oral azithromycin) were the standard management protocol. The mean age at PPROM was 29 weeks 2 days (±3 weeks), the mean age at birth was 30 weeks 5 days (±20 days). CRP levels were not different between groups. Uni/multivariate analysis showed that maternal CRP levels were not related with neonatal outcomes. Neonatal complications in PPROM are related with the degree of prematurity and maternal WBC counts.

There is growing evidence that a large number of very low birth weight infants are exhibiting neurobehavioral problems in the absence of cerebral palsy at follow-up that has extended into school age and adolescence. Many clinical factors (ie, chronic lung disease, recurrent apnea and bradycardia, transient hypothyroxemia of prematurity, hyperbilirubinemia, nutritional deficiencies, glucocorticoid exposure), as well as stressful environmental conditions, including infant-provider interaction, constant noise, and bright light, may act in combination to impact on the developing brain, even in the absence of overt hemorrhage and/or ischemia. Any potential intervention strategy designed to prevent cognitive and behavioral problems has to account for the numerous biological and clinical conditions and/or interventions, as well as postdischarge social and environmental influences.

Summary West J, Manchester B, Wright J, Lawlor DA, Waiblinger D. Reliability of routine clinical measurements of neonatal circumferences and research measurements of neonatal skinfold thicknesses: findings from the Born in Bradford study. Paediatric and Perinatal Epidemiology 2011. Assessing neonatal size reliably is important for research and clinical practice. The aim of this study was to examine the reliability of routine clinical measurements of neonatal circumferences and of skinfold thicknesses assessed for research purposes. All measurements were undertaken on the same population of neonates born in a large maternity unit in Bradford, UK. Technical error of measurement (TEM), relative TEM and the coefficient of reliability are reported. Intra-observer TEMs for routine circumference measurements were all below 0.4 cm and were generally within ±2-times the mean. Inter-observer TEM ranged from 0.20 to 0.36 cm for head circumference, 0.19 to 0.39 cm for mid upper arm circumference and from 0.39 to 0.77 cm for abdominal circumference. Intra and inter-observer TEM for triceps skinfold thickness ranged from 0.22 to 0.35 mm and 0.15 to 0.54 mm, respectively. Subscapular skinfold thickness TEM values were 0.14 to 0.25 mm for intra-observer measurements and 0.17 to 0.63 mm for inter-observer measurements. Relative TEM values for routine circumferences were all below 4.00% but varied between 2.88% and 14.23% for research skinfold measurements. Reliability was mostly between 80% and 99% for routine circumference measurements and ≥70% for most research skinfold measurements. Routine clinical measurements of neonatal circumferences are reliably assessed in Bradford. Assessing skinfolds in neonates has variable reliability, but on the whole is good. The greater intra-observer, compared with inter-observer, reliability for both sets of measurements highlights the importance of having a minimal number of assessors whenever possible. PMID:21281329

About 1-2% of infants born to mothers with Graves' disease or Hashimoto's thyroiditis develop neonatal hyperthyroidism because of transplacental passage of IgG stimulating TSH receptors (TRAb). To evaluate the effect of maternal total thyroidectomy on neonatal clinical course. We describe two brothers born to a mother with Graves' disease, before and after total thyroidectomy. The first child showed persistent tachycardia, the presence of TRAb and a laboratory pattern of hyperthyroidism. Lugol's solution was started and then propylthiouracil was added. Digitalis, furosemide and diazepam were necessary for treatment of heart failure, hypertension and irritability. On the 70th day of life, hormone serum levels normalized and treatment was interrupted. TRAb normalized by the third month of life. The second infant was born 2 years after the mother underwent total thyroidectomy. In spite of a laboratory pattern of hyperthyroidism and positivity to TRAb, he showed only considerable weight loss, and no therapy was required. TRAb may persist after total thyroidectomy: clinical and instrumental follow-up of the newborn is recommended.
Full Text Available Magnetic resonance imaging (MRI of the brain carried out during the neonatal period shows that 55-80% of extremely preterm infants display white matter diffuse excessive high signal intensity (DEHSI. Our aim was to study differences in developmental outcome at the age of 6.5 years in children born extremely preterm with and without DEHSI.This was a prospective cohort study of 83 children who were born in Stockholm, Sweden, between 2004 and 2007, born at gestational age of < 27 weeks + 0 days and who underwent an MRI scan of their brain at term equivalent age. The outcome measures at 6.5 years included testing 66 children with the modified Touwen neurology examination, the Movement Assessment Battery for Children 2, the Wechsler Intelligence Scale for Children-Fourth Edition, Beery Visual-motor Integration test-Sixth Edition, and the Strengths and Difficulties Questionnaire. Group-wise comparisons were done between children with and without DEHSI using Student t-test, Mann Whitney U test, Chi square test and regression analysis.DEHSI was detected in 39 (59% of the 66 children who were assessed at 6.5 years. The presence of DEHSI was not associated with mild neurological dysfunction, scores on M-ABC assessment, cognition, visual-motor integration, or behavior at 6.5 years.The presence of qualitatively defined DEHSI on neonatal MRI did not prove to be a useful predictor of long-term impairment in children born extremely preterm.

Retinal arterial tortuosity and venous dilation are hallmarks of plus disease, which is a severe form of retinopathy of prematurity (ROP). In this study, we examined whether short-term interruption of vascular endothelial growth factor (VEGF) signals leads to the formation of severe ROP-like abnormal retinal blood vessels. Neonatal rats were treated subcutaneously with the VEGF receptor (VEGFR) tyrosine kinase inhibitors, KRN633 (1, 5, or 10 mg/kg) or axitinib (10 mg/kg), on postnatal day (P) 7 and P8. The retinal vasculatures were examined on P9, P14, or P21 in retinal whole-mounts stained with an endothelial cell marker. Prevention of vascular growth and regression of some preformed capillaries were observed on P9 in retinas of rats treated with KRN633. However, on P14 and P21, density of capillaries, tortuosity index of arterioles, and diameter of veins significantly increased in KRN633-treated rats, compared to vehicle (0.5% methylcellulose)-treated animals. Similar observations were made with axitinib-treated rats. Expressions of VEGF and VEGFR-2 were enhanced on P14 in KRN633-treated rat retinas. The second round of KRN633 treatment on P11 and P12 completely blocked abnormal retinal vascular growth on P14, but thereafter induced ROP-like abnormal retinal blood vessels by P21. These results suggest that an interruption of normal retinal vascular development in neonatal rats as a result of short-term VEGFR inhibition causes severe ROP-like abnormal retinal vascular growth in a VEGF-dependent manner. Rats treated postnatally with VEGFR inhibitors could serve as an animal model for studying the mechanisms underlying the development of plus disease. Copyright © 2015 Elsevier Ltd.

Alteration of retinal angiogenesis during development leads to retinopathy of prematurity (ROP) in preterm infants, which is a leading cause of visual impairment in children. A number of clinical studies have reported higher rates of ROP in infants who had perinatal infections or inflammation, suggesting that exposure of the developing retina to inflammation may disturb retinal vessel development. Thus, we investigated the effects of systemic inflammation on retinal vessel development and retinal inflammation in neonatal rats. To induce systemic inflammation, we intraperitoneally injected 100 μl lipopolysaccharide (LPS, 0.25 mg/ml) or the same volume of normal saline in rat pups on postnatal days 1, 3, and 5. The retinas were extracted on postnatal days 7 and 14, and subjected to assays for retinal vessels, inflammatory cells and molecules, and apoptosis. We found that intraperitoneal injection of LPS impaired retinal vessel development by decreasing vessel extension, reducing capillary density, and inducing localized overgrowth of abnormal retinal vessels and dilated peripheral vascular ridge, all of which are characteristic findings of ROP. Also, a large number of CD11c+ inflammatory cells and astrocytes were localized in the lesion of abnormal vessels. Further analysis revealed that the number of major histocompatibility complex (MHC) class IIloCD68loCD11bloCD11chi cells in the retina was higher in LPS-treated rats compared to controls. Similarly, the levels of TNF-α, IL-1β, and IL-12a were increased in LPS-treated retina. Also, apoptosis was increased in the inner retinal layer where retinal vessels are located. Our data demonstrate that systemic LPS-induced inflammation elicits retinal inflammation and impairs retinal angiogenesis in neonatal rats, implicating perinatal inflammation in the pathogenesis of ROP.

Sepsis-related morbidity and mortality are major problems in NICU. Preterm neonates display clinical characteristics that make them prone to infections. Due to the high frequency of severe neurodevelopmental sequelae in survivors, the best possible strategy to manage sepsis in NICU is to prevent them. Hygiene, cohorting, stewardship on use of H2-blockers, steroids and broad-spectrum antibiotic are mandatory, as well as proper management of central venous accesses and surgical devices. In addition, clinical research offers the opportunity of adopting pharmacological preventative strategies such as use of palivizumab to prevent RSV infection, use of fluconazole to prevent fungal sepsis, use of probiotics and lactoferrin to enhance the innate immunity, and use of pagibaximab to prevent staphylococcal sepsis.

To examine the neonatal mortality and morbidity of infants born at CPR) immediately after birth. In this retrospective cohort study, we performed secondary analyses of data from infants born at Neonatal Network between January 2010 and December 2011. Infants were divided into two groups based on birth weight (neonatal morbidity and mortality compared using bivariate and multivariate analyses. Of the 8033 eligible infants, 419 (5.2%) received DR-CPR. For infants weighing CPR, whereas 3.4% (outborn: 9.6%, inborn: 2.2%) of those weighing ≥1000 g received DR-CPR. If infants received DR-CPR there was increased risk of mortality, bronchopulmonary dysplasia (BPD) and severe brain injury. Logistic regression analysis showed DR-CPR was associated with increased mortality (adjusted odds ratio [aOR]: 2.09, 95% CI [1.39, 3.14]) in infants born weighing CPR was associated with increased mortality (aOR: 7.16, 95% CI [3.88, 13.2]), severe brain injury (aOR: 3.08, 95% CI [1.82, 5.22]), BPD (aOR: 2.14, 95% CI [1.25, 3.65]), pneumothorax (aOR: 3.11, 95% CI [1.53, 6.31]) and intestinal perforation (aOR: 3.47, 95% CI [1.46, 8.24]). DR-CPR is associated with increased risk of mortality and morbidity especially in preterm infants born weighing ≥1000 g. Long-term neurodevelopmental follow up is warranted for these infants.
Full Text Available Severe combined immunodeficiency (SCID, a primary immunodeficiency arising from variable defects in lymphocyte development and survival, is characterized by significant deficiency of thymus derived (T- lymphocytes and variable defects in the B-lymphocyte population. Newborn screening for SCID is based on detection of low numbers of T-cell receptor excision circles (TRECs by real time quantitative PCR (RT-qPCR. This screening allows for early identification of individuals with SCID and other disorders characterized by T-lymphopenia. Higher rates of abnormal screens are commonly seen in premature and critically ill neonates, often representing false positives. It is possible that many abnormal screens seen in these populations are result of conditions that are characterized by systemic inflammation or stress, possibly in the context of stress-induced thymic involution. We present a case of a male infant delivered at 27 weeks, 6 days of gestation, with severe intrauterine growth restriction who had an abnormal TREC screen and a massive perivillous fibrin deposition (MPFD of the placenta. This association has not been reported previously. We are raising the awareness to the fact that conditions, such as MPFD, that can create adverse intrauterine environment are capable of causing severe stress-induced thymic involution of the fetus which can present with abnormal TREC results on newborn screening.

The incubator environment is essential for optimal physiological functioning and development of the premature infant but the infant is ultimately required to make a successful transfer from incubator to open cot in order to be discharged from hospital. Criteria for transfer lack a systematic approach because no clear, specific guideline predominates in clinical practice. Practice variation exists between continents, regions and nurseries in the same countries, but there is no recent review of current practices utilised for transferring premature infants from incubators to open cots. To document current practice for transferring premature infants to open cots in neonatal nurseries. A descriptive, cross-sectional survey. Twenty-two neonatal intensive care units and fifty-six high dependency special care baby units located in public hospitals in Australia and New Zealand. A sample of 78 key clinical nursing leaders (nurse unit managers, clinical nurse consultants or clinical nurse specialists) within neonatal nurseries identified through email or telephone contact. Data were collected using a web-based survey on practice, decision-making and strategies utilised for transferring premature infants from incubators to open cots. Descriptive statistics (frequencies and crosstabs) were used to analyse data. Comparisons between groups were tested for statistical significance using Chi-squared or Fisher's exact test. Significant practice variation between countries was found for only one variable, nursing infants clothed (p=0.011). Processes and practices undertaken similarly in both countries include use of incubator air control mode, current weight criterion, thermal challenging, single-walled incubators and heated mattress systems. Practice variation was significant between neonatal intensive care units and special care baby units for weight range (p=0.005), evidence-based practice (p=0.004), historical nursery practice (p=0.029) and incubator air control mode (p=0

We investigated pharmacokinetics and clinical effects of flomoxef sodium (6315-S, FMOX) in neonates and premature infants. These results are summarized as follows: 1. Pharmacokinetics (1) Plasma concentration (Ct) and half-lives (T1/2) were determined upon after intravenous one-shot injection (i.v.) of FMOX to neonates of different day-age groups (0-3 (n = 25), 4-7 (n = 18), 8-28 (n = 32) days of birth). At a dose of 10 mg/kg. i.v., mean C30 (30 minutes concentration) values were 21.2, 21.8 and 21.3 micrograms/ml, respectively, in the different groups mentioned above, and the mean T1/2 values were 3.37, 1.85 and 1.63 hours. At 20 mg/kg i.v., mean C15 (15 minutes concentration) values were 54.4, 51.4 and 50.7 micrograms/ml, and mean T1/2's were 2.99, 2.32 and 1.79 hours, respectively. At a dose of 40 mg/kg i.v., mean C15 values were 104.0, 95.9 and 99.2 micrograms/ml, and the mean T1/2's were 3.40, 1.20 and 1.80 hours, respectively. (2) Plasma concentrations and T1/2 after intravenous one-shot injection of FMOX in premature infants in group (0-3 (n = 14), 4-7 (n = 10), 8-28 (n = 13) days of birth). Mean C15's at doses of 10, 20 and 40 mg/kg in the different groups of infants were 24.0, 28.6, 21.7 and 54.0, 54.6, 55.5 and 98.2, 93.0, 106.0 micrograms/ml, and T1/2's were 4.10, 2.53, 2.57 and 4.28, 2.27, 3.02 and 4.66, 2.86, 2.09 hours, respectively. Mean Cmax values were clearly dose dependent, and mean T1/2 values tended to be longer in premature infants compared to neonates. (3) Urinary recovery rate of FMOX after intravenous injection in neonates and premature infants. Mean urinary recovery rates of FMOX in the first 6 hours after i.v. (one-shot) at doses of 10, 20 and 40 mg/kg to neonates and premature infants were 38.9-62.8% in the neonates and 30.7-61.5% in the premature infants. (4) Plasma concentrations and urinary recovery rates upon 1 hour drip infusion of 20 mg/kg in the neonate groups (or the premature infant groups) as follows: Mean C50 values were 31
Full Text Available Background: To understand the characteristics, ophthalmic outcomes, and risk factors of retinopathy of prematurity (ROP in patients with birth weight (BW greater than 1500 g. The applicability of the ROP screening criteria to the Taiwanese population was also examined. Methods: The study included 104 eyes from 54 ROP patients who had BW greater than 1500 g from 1981 to 2008. Demographic information, disease courses, ophthalmic outcomes, and possible systemic risk factors were recorded. The infants were divided into groups of mild and severe ROP for a risk factor analysis. Results: The mean gestational age (GA of the infants was 31 ± 1.3 weeks, and the mean BW was 1675 ± 249 g. Mild ROP regressed in 94 eyes (90%, and 10 eyes (10% developed severe ROP. After various treatments, the regression rates for prethreshold or threshold ROP (n = 8 and stage 4 ROP (n = 2 were 100% and 50%, respectively. Forty-eight patients (85% had at least three associated systemic risk factors. A multiple logistic regression analysis revealed that patients with an intraventricular hemorrhage were found to have an increased chance of developing severe ROP, especially those with BW greater than 1500 g (p = 0.015. There was also a significant association between patients who had severe ROP and an increased risk of having cerebral palsy (CP at 1.5 years of age (p = 0.013. Conclusion: The majority of patients with BW greater than 1500 g developed mild ROP. However, advanced ROP with poor visual outcome was also encountered in some patients.
Reducing hospital expenditures with the COPE (Creating Opportunities for Parent Empowerment) program for parents and premature infants: an analysis of direct healthcare neonatal intensive care unit costs and savings.
Melnyk, Bernadette Mazurek; Feinstein, Nancy Fischbeck
More than 500,000 premature infants are born in the United States every year. Preterm birth results in a multitude of negative adverse outcomes for children, including extended stays in the neonatal intensive care unit (NICU), developmental delays, physical and mental health/behavioral problems, increased medical utilization, and poor academic performance. In addition, parents of preterms experience a higher incidence of depression and anxiety disorders along with altered parent-infant interactions and overprotective parenting, which negatively impact their children. The costs associated with preterm birth are exorbitant. In 2005, it is estimated that preterm birth cost the United States $26.2 billion. The purpose of this study was to perform a cost analysis of the Creating Opportunities for Parent Empowerment (COPE) program for parents of premature infants, a manualized educational-behavioral intervention program comprising audiotaped information and an activity workbook that is administered to parents in 4 phases, the first phase commencing 2 to 4 days after admission to the NICU. Findings indicated that the COPE program resulted in cost savings of at least $4864 per infant. In addition to improving parent and child outcomes, routine implementation of COPE in NICUs across the United States could save the healthcare system more than $2 billion per year.

Chronic respiratory morbidity is a common complication of premature birth, generally defined by the presence of bronchopulmonary dysplasia, both clinically and in trials of respiratory therapies. However, recent data have highlighted that bronchopulmonary dysplasia does not correlate with chronic respiratory morbidity in older children born preterm. Longitudinally evaluating pulmonary morbidity from early life through to childhood provides a more rational method of defining the continuum of chronic respiratory morbidity of prematurity, and offers new insights into the efficacy of neonatal respiratory interventions. The changing nature of preterm lung disease suggests that a multimodal approach using dynamic lung function assessment will be needed to assess the efficacy of a neonatal respiratory therapy and predict the long-term respiratory consequences of premature birth. Our aim is to review the literature regarding the long-term respiratory outcomes of neonatal respiratory strategies, the difficulties of assessing dynamic lung function in infants, and potential new solutions.

The aim of this study was to investigate the effect of recombinant human erythropoietin (rHu-EPO) on oxygen affinity and adequate oxygen delivery to the tissues of stable premature infants. 36 very-low-birth-weight infants were randomly assigned to either receive rHu-EPO (200 units/kg every other day) or not, and both groups were supplemented with iron, folic acid and vitamin E. Arterial blood gases, oxygen saturation, complete blood counts, fetal haemoglobin, 2,3-diphosphoglycerate (2,3-DPG) and blood lactate were analysed weekly, from the 1st week till discharge. Patients in the two groups were comparable. There was a trend in increasing lactate values towards the 4th to 5th weeks of life, which did not reach statistical significance. There was no correlation between lactate values and the studied variables (pH, BE, oxygen saturation). In 35 transfusions, pre- and 24 h post-transfusion blood lactate status was studied. In 23 of them, a decrease in post-transfusion lactate was noticed, whilst an increased post-transfusion level was shown in 10 cases and no change in 2 cases. The mean pre-transfusion lactate value was significantly higher than the post-transfusion one (24.04 +/- 11.9 mg/dl before and 16.27 +/- 8.5 mg/dl after transfusion; p = 0.0025). In both groups there was a steady rise in 2,3-DPG concentration over the period of study, and the 2,3-DPG values at the end of our study were significantly increased in the rHu-EPO group (rHu-EPO 5.98 +/- 0.9, control 4.84 +/- 0.7; p = 0.04). In conclusion, the use of rHu-EPO did not affect blood lactate levels compared to the control group. Regarding oxygen affinity, it seems that rHu-EPO causes a shift of the oxy-haemoglobin dissociation curve to the right. This is a previously unreported effect of rHu-EPO and its clinical use may, thus, confer to preterm babies an added advantage.

Full Text Available BACKGROUND: The objective of this study was to determine whether acute histologic chorioamnionitis is associated with adverse neonatal outcomes in late preterm infants who were born after preterm PROM. METHODOLOGY/PRINCIPAL FINDINGS: The relationship between the presence of acute histologic chorioamnionitis and adverse neonatal outcome was examined in patients with preterm PROM who delivered singleton preterm newborns between 34 weeks and 36 6/7 weeks of gestation. Nonparametric statistics were used for data analysis. The frequency of acute histologic chorioamnionitis was 24% in patients with preterm PROM who delivered preterm newborns between 34 weeks and 36 6/7 weeks of gestation. Newborns born to mothers with histologic chorioamnionitis had significantly higher rates of adverse neonatal outcome (74% vs 51%; p<0.005 than those without histologic chorioamnionitis. This relationship remained significant after adjustment for gestational age at preterm PROM, gestational age at delivery, and exposure to antenatal corticosteroids. CONCLUSIONS/SIGNIFICANCE: The presence of acute histologic chorioamnionitis is associated with adverse neonatal outcome in late preterm infants born to mothers with preterm PROM.

Saumil Ashvin Desai
Full Text Available Aim: This study aimed to compare Neonatal Pain, Agitation, and Sedation Scale (N-PASS with Premature Infant Pain Profile (PIPP for the assessment of acute prolonged pain in ventilated neonates. Methods: This study was conducted in two phases. In phase 1 of the study, we assessed whether neonates on assisted ventilation experienced acute prolonged pain. In phase 2, the aim was to compare N-PASS with PIPP for the assessment of acute prolonged pain in neonates on assisted ventilation.. Design: This is a prospective observational study. Study Setting and Duration: This study was conducted at a tertiary care neonatal intensive care unit for 6 months. Inclusion Criteria: Neonates on assisted ventilation for >48 h were selected for this study. Exclusion Criteria: Neonates with lethal congenital anomalies and severe encephalopathy were excluded from the study. N-PASS and PIPP tools were used to assess acute prolonged pain in ventilated neonates. Taking PIPP as gold standard and N-PASS as a new test, the correlation coefficient was calculated. The sensitivity, specificity, positive predictive value, and negative predictive value were also computed. The time taken to administer the tools was also computed. Results: The average PIPP score for ventilated neonates was 8.33. The correlation coefficient of N-PASS when compared to PIPP was 0.62. The average time taken to apply the N-PASS scale was 4.42 min as compared to 8.20 min for PIPP scale. In term neonates, the sensitivity, specificity, positive predictive value, and negative predictive value of N-PASS were 75%, 100%, 100%, and 60%, respectively. The corresponding values in preterm neonates were lesser. Conclusions: The study proves that neonates on assisted ventilation experience acute prolonged pain. N-PASS is clinically reliable and valid to assess acute prolonged pain in ventilated term neonates. The N-PASS is quicker than PIPP in assessing acute prolonged pain in ventilated neonates. Future
Sepsis is one of the most common causes of neonatal deaths globally. Most sepsis-related deaths occur in low-income and middle-income countries, where the epidemiology of neonatal sepsis remains poorly understood. Most of these countries lack proper surveillance networks, hampering accurate assessment of the burden of sepsis, implementation of preventive measures, and investment in research. We report results of neonates born in hospital from a multicentre collaboration on neonatal sepsis. In this cohort study, dedicated research teams prospectively followed up neonates born in one of three tertiary care centres in Delhi, India (Vardhaman Mahavir Medical College, Maulana Azad Medical College, and All India Institute of Medical Sciences [coordinating centre]) and subsequently admitted to the intensive care unit. Neonates were followed up daily until discharge or death. On clinical suspicion, neonates underwent sepsis work-up including blood cultures. The isolated organisms were identified and tested for antimicrobial susceptibility. We defined Gram-negative isolates resistant to any three of five antibiotic classes (extended-spectrum cephalosporins, carbapenems, aminoglycosides, fluoroquinolones, and piperacillin-tazobactam) as multidrug resistant. 13 530 neonates of 88 636 livebirths were enrolled between July 18, 2011, and Feb 28, 2014. The incidence of total sepsis was 14·3% (95% CI 13·8-14·9) and of culture-positive sepsis was 6·2% (5·8-6·6). Nearly two-thirds of total episodes occurred at or before 72 h of life (defined as early onset; 1351 [83%] of 1980). Two-thirds (645 [64%]) of 1005 isolates were Gram-negative including, Acinetobacter spp (22%), Klebsiella spp (17%), and Escherichia coli (14%). The pathogen mix in early-onset sepsis did not differ from that of late-onset sepsis (ie, after 72 h). High rates of multidrug resistance were observed in Acinetobacter spp (181/222, 82%), Klebsiella spp (91/169, 54%), and Escherichia coli (52/137, 38

The aim of this study was to report the gestational age (GA) and birth weight (BW) distribution of premature babies who needed treatment for retinopathy of prematurity (ROP) and to assess the timing of the treatment. The records of 9008 infants who were screened for ROP were examined and 556 infants who underwent laser therapy for ROP were reviewed. Sex, GA, BW, postnatal age, and postmenstrual (PM) age at the time of laser therapy were recorded. The babies were classified as in-born (Group 1) and out-born infants (Group 2). The mean GA was 27.3 weeks (range: 22-33 weeks) and the mean BW was 991.1 g (range: 520-2160 g). Of the treated infants, 7.0% were born later than 32 weeks and 8.3% were born over 1500 g. The mean postnatal age was 9.48 weeks (range: 5-22 weeks) and the mean PM age was 36.72 weeks (range: 29-48 weeks) at the time of treatment. Mean BWs and GAs were significantly higher and the mean postnatal age at the time of laser therapy was significantly earlier in Group 2. Infants with severe ROP had a wider range of BWs and GAs compared to those from developed countries and earlier treatment was needed for out-born infants.

To report the patterns and causes of neonatal death from a tertiary care neonatal intensive care unit over a period of four years. This is a retrospective cohort study where four years data (January 2006 - December 2009) of all inborn neonatal admissions and deaths were collected from the neonatal intensive care unit at Sultan Qaboos University hospital on predesigned forms. All out born admissions and deaths were excluded. The causes of neonatal death were classified using Wigglesworth's classification. The number of inborn live births during the study period was 10064 and the total number of inborn neonatal admissions was 1475. The total deaths (neonatal and post neonatal) at the neonatal intensive care unit was 73 (63 inborn and 10 out born). Among the inborn, five deaths were post neonatal deaths and hence, excluded from analysis. Among the remaining inborn neonatal deaths (n=58), 34 (59%) were males and 24 (41%) were females. The number of neonatal admissions increased over the years during the study period from 248 to 356, while the number of deaths also increased from 10 deaths in 2006, to 20 deaths in 2009. The primary causes of neonatal deaths were prematurity and its complications 52% (n=30). Lethal congenital malformations lead to 17 (29%) newborn deaths, specific diagnosis in 7 newborns (12%), and birth asphyxia in four (7%) of cases. There was an increasing trend of neonatal admissions and deaths among inborn babies. Prematurity, with sepsis as its major complication and congenital malformations were the leading cause of neonatal mortality.

Full Text Available Preterm delivery is the single most important cause of perinatal morbidity and mortality. In Chile, preterm births have increased in the past decade, although neonatal morbidity and mortality attributable to it shows a downward trend, thanks to improvements in neonatal care of premature babies, rather than the success of obstetric preventive and therapeutic strategies. This article describes clinical entities, disease processes and conditions that constitute predisposing factors of preterm birth, as well as an outline for the prevention and clinical management of women at risk of preterm birth.

Full Text Available Abstract Background Cleft lip and/or palate (CL/P increase mortality and morbidity risks for affected infants especially in less developed countries. This study aimed at assessing the effects of systematic pediatric care on neonatal mortality and hospitalizations of infants with cleft lip and/or palate (CL/P in South America. Methods The intervention group included live-born infants with isolated or associated CL/P in 47 hospitals between 2003 and 2005. The control group included live-born infants with CL/P between 2001 and 2002 in the same hospitals. The intervention group received systematic pediatric care between the 7th and 28th day of life. The primary outcomes were mortality between the 7th and 28th day of life and hospitalization days in this period among survivors adjusted for relevant baseline covariates. Results There were no significant mortality differences between the intervention and control groups. However, surviving infants with associated CL/P in the intervention group had fewer hospitalization days by about six days compared to the associated control group. Conclusions Early systematic pediatric care may significantly reduce neonatal hospitalizations of infants with CL/P and additional birth defects in South America. Given the large healthcare and financial burden of CL/P on affected families and the relatively low cost of systematic pediatric care, improving access to such care may be a cost-effective public policy intervention.

To investigate some selected nutrients status in the neonates born to diabetic and non-diabetic mothers a prospective study was carried out. From the Obstetric Unit of Bangladesh Institute of Rehabilitation in Diabetes, Endocrine and Metabolic disorder (BIRDEM) Hospital, Dhaka, Bangladesh, 236 newborns were recruited; 74 from diabetic, 59 from gestational diabetic and 103 from non-diabetic mothers group for this study. Cord-serum levels of Cu, Zn, Fe, Mg, Ca and ascorbic acid were investigated, and some anthropometric measurements were recorded to correlate with the nutrient levels. Fe was found significantly higher (p<0.05) whereas, ascorbic acid was found significantly lower (p<0.05) in diabetic group compared with other two groups. However, Mg and Ca levels were found significantly higher (p<0.05) in non-diabetic group. There was no significant difference observed in Cu, Zn levels for the 3 groups. Ca level was significantly correlated with birth weight and length of the neonates. These data suggests that diabetes has some effects on fetal growth and its nutritional status that also reflect the socio-economical status of the families of the neonates. (author)

The neonatal intensive care unit (NICU) provides life-saving medical care for an increasing number of newborn infants each year. NICU care, while lifesaving, does have attendant consequences which can include repeated activation of the stress response and reduced maternal interaction, with possible negative long-term impacts on brain development. Here we present a neuroscientific framework for considering the impact of music on neurodevelopment in the NICU of infants born preterm and evaluate current literature on the use of music with this population to determine what is most reliably known of the physiological effects of music interventions. Using online academic databases we collected relevant, experimental studies aimed at determining effects of music listening in infants in the NICU. These articles were evaluated for methodological rigor, ranking the 10 most experimentally stringent as a representative sample. The selected literature seems to indicate that effects are present on the cardio-pulmonary system and behavior of neonates, although the relative effect size remains unclear. These findings indicate a need for more standardized longitudinal studies aimed at determining not only whether NICU music exposure has beneficial effects on the cardio-pulmonary system, but also on the hypothalamic-pituitary-adrenal axis, brain structures, and cognitive behavioral status of these children as well. Provides a neuroscience framework for considering how music might attenuate stress in neonatal intensive care unit (NICU) infants. Considers how repeated stress may cause negative neurodevelopmental impacts in infants born preterm. Posits epigenetics can serve as a mechanistic pathway for music moderating the stress response. © 2018 Mac Keith Press.

Plain radiographs for infants in the neonatal intensive care unit are obtained using the portable X-ray equipment in order to evaluate the neonatal lungs and also to check the position of the tubes and catheters used for monitoring critically-ill neonates. Neonatal respiratory distress is caused by a variety of medical or surgical disease conditions. Clinical information about the gestational week, respiratory symptoms, and any events during delivery is essential for interpretation of the neonatal chest radiographs. Awareness of common chest abnormality in the prematurely born or term babies is also very important for chest evaluation in the newborn. Furthermore, knowledge about complications such as air leaks and bronchopulmonary dysplasia following treatment are required to accurately inform the clinicians. The purpose of this article was to briefly review radiographic findings of chest diseases in newborns that are relatively common in daily practice.

Full Text Available Background Apnea of prematurity (AOP is a developmental disorder that affects the premature newborns frequently. One of the new non-drug methods for controlling apnea attacks is olfactory stimulation. The aim of this study was to determine the effect of olfactory stimulation by vanilla on the rate of apnea attacks in neonates with AOP. Materials and Methods: This study is a single-blind randomized clinical trial study. The study samples included a total of 40 premature neonates with AOP who were admitted to the neonatal Intensive care unit (NICU of Shahid Sadoughi hospital in Yazd, Iran, in 2016 and were assigned randomly in experimental (n=20, and control (n=20 groups. The experimental group was exposed to cotton impregnated with 2ml of vanillin extractfor 24 hours. The number of apnea attacks, heart rate, and arterial oxygen saturation (SaO2 level were measured before, during and after intervention for three consecutive days. Data analysis was performed using statistical analysis in SPSS version 22.0 software. Results: The results showed that there was no significant difference between the two groups in terms of mean number of apnea attacks (p>0.05. However, there was a significant difference between in the experimental group on the first day (2.84 ± 1.25, and second day (1.63 ± 1.01 in terms of the mean number of attacks. Also, there was a significant difference between the mean heart rate and SaO2 level in both the experimental and control groups (p

We studied the effect of antenatal corticosteroids on the incidence of respiratory disorders in singleton neonates born between 34 and 36 weeks of gestation. Retrospective analysis was conducted of the incidence of respiratory distress syndrome (RDS) and other respiratory disorders (need for mechanical ventilation, continuous positive airway pressure, and prolonged oxygen therapy) among singleton neonates delivered between 34 and 36 weeks of gestation who were exposed to antenatal corticosteroids, compared with neonates who were not exposed. Statistical analyses included two-tailed T tests, two-way analysis of variance for continuous data, and chi-square analysis for ratios. A probability of 0.05 was considered significant. Between January 1, 2000, and December 31, 2004, 1078 neonates were born between 34 and 36 weeks of gestation. Information regarding antenatal corticosteroids was available in 1044: 574 neonates (53.2%) were exposed to antenatal corticosteroids and 470 (43.6%) were not. One thousand and eighteen neonates were admitted to the neonatal intensive care unit. Respiratory disorders were diagnosed in 140 of those exposed to antenatal steroids (24.4%) and in 382 of the nonexposed (81.3%) ( P < 0.0001). Two hundred and ten neonates (20.6%) developed RDS: Of those, 43 were exposed to antenatal corticosteroids and 167 were not (incidence of RDS was 7.5% and 35.5%, respectively; P = 0.0001). The beneficial effects of corticosteroids were similar in both genders. It appears that the exposure of singleton pregnancies to antenatal corticosteroids between 24 and 34 weeks of gestation is associated with a significantly lower incidence of respiratory disorders among neonates born at 34 to 36 weeks of gestation. Further studies are needed to determine whether administering antenatal steroids to women experiencing preterm labor after 34 weeks of gestation would be associated with a similar beneficial effect.
Full Text Available Background: Considering all the latest achievements in neonatal respiratory care, bronchopulmonary dysplasia (BPD is still among the most prevalent morbidity causes in premature infants. Involvement in this process results in longer period of hospitalization for the newborn and in the long run makes the living conditions more difficult. Taking the multifactorial pathogenesis into account, approaches to tackle chronic lung disease (CLD are mainly focused on interventions and prevention procedures. This study tries to investigate the potential capability of inhaled budesonide in the prevention of BPD in newborns with gestational age of <28 weeks with the respiratory distress syndrome (RDS. Methods: This study was a randomized clinical trial done on seventy newborns with gestational ages of 23–28 weeks with RDS in Isfahan Shahid Beheshti Educational Hospital from June 2014 to April 2016. Patients were randomly assigned to two groups of intervention with budesonide and control. There were 35 newborns in each group. Upon recording demographic characteristics, the newborns in two groups were compared based on the length of noninvasive ventilation, the need for invasive mechanical ventilation, the number of surfactant administrations, pneumothorax, intraventricular hemorrhage, patent ductus arteriosus (PDA, CLD, and death. Results: The length of the need for nasal continuous positive airway pressure showed no statistically significant difference between the groups (P = 0.54. The number of newborns who needed invasive mechanical ventilation also revealed no meaningful difference (P = 0.14. Similarly, the number of newborns who were characterized as affected by CLD also showed no significant difference between the groups (P = 0.053. Moreover, the number of newborns who experienced pneumothorax was not significantly different for the groups (P = 0.057. The number of newborns who received three administrations of surfactant had also no statistically

Herpes simplex virus (HSV) infection of the neonate is uncommon, but genital herpes infections in adults are very common. Thus, although treating an infant with neonatal herpes is a relatively rare occurrence, managing infants potentially exposed to HSV at the time of delivery occurs more frequently. The risk of transmitting HSV to an infant during delivery is determined in part by the mother's previous immunity to HSV. Women with primary genital HSV infections who are shedding HSV at delivery are 10 to 30 times more likely to transmit the virus to their newborn infants than are women with recurrent HSV infection who are shedding virus at delivery. With the availability of commercial serological tests that reliably can distinguish type-specific HSV antibodies, it is now possible to determine the type of maternal infection and, thus, further refine management of infants delivered to women who have active genital HSV lesions. The management algorithm presented herein uses both serological and virological studies to determine the risk of HSV transmission to the neonate who is delivered to a mother with active herpetic genital lesions and tailors management accordingly. The algorithm does not address the approach to asymptomatic neonates delivered to women with a history of genital herpes but no active lesions at delivery.

To determine whether preterm premature rupture of membranes (PPROM) before 24 weeks is an independent risk factor for poor outcome in preterm neonates. A retrospective comparative cohort study was conducted, including viable premature infants born between 25 and 34-weeks gestation. Each preterm case with early PPROM was matched with two preterm controls of the same gestational age at birth, sex and birth date and who were born spontaneously with intact membranes. Logistic regression was performed to identify independent risk factors associated with composite respiratory and perinatal adverse outcomes for the overall population of preterm infants. Thirty-five PPROM cases were matched with 70 controls. Extreme prematurity (26-28 weeks) was an independent risk factor for composite perinatal adverse outcomes [odds ratio (OR) 43.9; p = 0.001]. Extreme prematurity (OR 42.9; p = 0.001), PPROM (OR 7.1; p = 0.01), male infant (OR 5.2; p = 0.02) and intrauterine growth restriction (IUGR, OR 4.8; p = 0.04) were factors for composite respiratory adverse outcomes. Preterm premature rupture of membranes before viability represents an independent risk factor for composite respiratory adverse outcomes in preterm neonates. Extreme prematurity may represent the main risk factor for both composite respiratory and perinatal adverse outcomes. ©2013 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.
Full Text Available Congenital cytomegalovirus (cCMV infection contributes to considerable long-term sequelae in neonates and children all over the world. The association between viral genotypes and severity of clinical cytomegalovirus (CMV infection is yet to be defined. The objective of this study was to find the impact of active CMV infection during pregnancy and the clinical significance of genotypes in neonates with congenital cytomegalovirus infections in Pakistan.A total of 409 blood samples from pregnant women seeking health care services at the two antenatal hospitals of Islamabad during January to December 2012 were tested by ELISA and nested-PCR. Pregnant women with active infection (detected as IgM positive, PCR positive or positive on both assays were followed until delivery, to detect the outcome of overt cCMV infection in neonates. Genetic characterization of CMV strains was performed by sequence analysis of envelope glycoproteins: gB, gN and gH to detect the contributing CMV genotypes.The seroprevalence of anti-CMV IgG and IgM was 97.5% (399 out of 409 and 12.7% (52 out of 409, respectively, while 20% (82/409 pregnant women were found positive for CMV DNA by PCR. Logistic regression analysis showed a significant association of active infection with parity [OR = 2.56, 95% CI = 1.82-2.62, p = 0.04], febrile illness [OR = 1.84, 95% CI = 1.76-3.65, p = 0.01] and jaundice [OR = 22.5, 95% CI = 4.53-85.02, p = 0.002]. We were able to isolate virus in 41 out of 70 neonates; 36.6% (15 out of 41 of them were symptomatic at birth while 63.4% (26 out of 41 were asymptomatic. The most prominent clinical feature observed in symptomatic neonates was hepatosplenomegaly (26.6%; 4 out of 15. All three genotypes gB, gN and gH were found with the highest frequency of gB1 genotype, found in 75% infants with hepatic damage. Phylogenetic analysis of Pakistani strains showed 96%-100% homology to their prototype strains.Active CMV infection during pregnancy is a major cause
Full Text Available Abstract Background Mothers of preterm infants are considered at higher risk for depressive symptoms, higher than for mothers of healthy term infants. Predictors of depressive symptoms in mothers of preterm infants are not yet well established. Immigrant mothers of term infants have higher prevalence of depressive symptoms than Canadian born mothers but the relative prevalence for immigrant mothers of preterm infants is unknown. This study had two aims: (i to investigate the prevalence of depressive symptoms in immigrant as compared to Canadian born mothers of preterm infants, and (ii to determine what factors are associated with depressive symptoms in mothers of preterm infants. Methods This is a multi-site, cross sectional study of mothers whose preterm infants required hospitalization in neonatal intensive care unit (NICU. Consecutive eligible mothers (N = 291 were recruited during the week prior to their infant’s NICU discharge. Mothers completed a self-administered questionnaire booklet of validated psychosocial/cultural measures including the Center for Epidemiological Studies Depression Scale (CES-D, Parental Stressor Scale:NICU, General Functioning Subscale of the McMaster Family Assessment Device, Social Support Index, and Vancouver Index of Acculturation; and demographic characteristics questions. Infant characteristics included gestational age, birth weight, sex, singleton/multiple birth, and Score for Neonatal Acute Physiology-II. Results Immigrant mothers (N = 107, when compared to Canadian born mothers (N = 184, reported more depressive symptoms, poorer family functioning, less social support, and less mainstream acculturation. Hierarchical regression for a subsample of 271 mothers indicated that single parent status, high stress, poorer family functioning, and less social support were associated with increased depressive symptoms and accounted for 39% of the variance on the CES-D. Immigrant status did not contribute

Infant characteristics included gestational age, birth weight, sex, singleton/multiple birth, and Score for Neonatal Acute Physiology-II. Results Immigrant mothers (N = 107), when compared to Canadian born mothers (N = 184), reported more depressive symptoms, poorer family functioning, less social support, and less mainstream acculturation. Hierarchical regression for a subsample of 271 mothers indicated that single parent status, high stress, poorer family functioning, and less social support were associated with increased depressive symptoms and accounted for 39% of the variance on the CES-D. Immigrant status did not contribute significantly to the final

Several socio-environmental risk factors causea large number of children born prematurely, and without neurological disorders, to have low scores in their development, particularly in the cognitive and socio-emotional skills areas, thus evidencing a potential future risk. Strengthening bonds with the family and caregivers is critical for their adequate development. This article reports on the experience of an interdisciplinary team from Hospital Eva Perón de Tucumán, who designed a program called "Learning Through Play"for the promotion of child development and aimed at parents of preterm infants seen at the Follow-up Outpatient Clinic and the Department of Social Services, with the collaboration of the Department of Nutrition.

To compare the neonatal outcome in twin gestations complicated by prolonged preterm premature rupture of membranes (PPROM). Between the years 2000 and 2010 we identified 48 women with twin pregnancies who were diagnosed as having PPROM and a latency period to delivery >24h. We compared the neonatal morbidity and mortality between the presenting and non-presenting twins, assuming that the rupture occurred in the lower sac. Importantly, in 30 women we were able to identify the location of the ruptured sac by ultrasound examination demonstrating oligohydramnion. In these 30 cases, neonatal outcome of fetuses in the ruptured sac and those in the intact sac were compared. The median gestational age was 31 weeks (range 28-33) with a median latency period between PPROM and delivery of 9 days (range 1-18). Of the identified ruptures 90% (27/30) occurred in the lower sac (presenting twin). There was no significant difference between the presenting and non-presenting twin in terms of neonatal morbidity and mortality. Moreover, no difference was found when fetuses with ruptured sac were compared to those with intact membrane sac. Importantly, the outcomes were not affected by the length of the latency period. The current study results demonstrated that the outcome of fetuses exposed to prolonged preterm rupture of membranes is similar to that of fetuses with intact membranes. Our data suggest that rupture of membranes per se did not cause any deleterious clinical manifestations or lead to clinical discordant inflammation and poor neonatal outcome, supporting a conservative management of twin pregnancies with PPROM.

The Born-Alive Infants Protection Act (BAIPA), passed by Congress in 2002, has attracted little publicity. Its purposes were, in part, "to repudiate the flawed notion that a child's entitlement to the protections of the law is dependent on whether that child's mother or others want him or her." Understood as antiabortion rhetoric, the bill raised little concern among physicians at the time of legislative hearings and passed in both Houses by overwhelming majorities, hardly suggesting contentious legislation. After its signing into law, the Neonatal Resuscitation Program (NRP) Steering Committee issued an opinion stating that "[BAIPA] should not in any way affect the approach that physicians currently follow with respect to the extremely premature infant." This interpretation of the law, however, may have been short sighted. In April 2005, the US Department of Health and Human Services (DHHS) brought life to the BAIPA, announcing: "As a matter of law and policy, [DHHS] will investigate all circumstances where individuals and entities are reported to be withholding medical care from an infant born alive in potential violation of federal statutes." The agency issued instructions to state officials on how the definitional provision within the BAIPA interacts with the Emergency Medical Treatment and Labor Act (EMTALA) and the Child Abuse Prevention and Treatment Act (CAPTA). These interagency memoranda potentially resurrect dormant governmental oversight of newborn-treatment decisions and thus may have influence over normative neonatal practice. Under the BAIPA, the DHHS interprets EMTALA to protect all "born-alive" infants; hospitals and physicians violating regulatory requirements face agency-sanctioned monetary penalties or a "private right of action by any individual harmed as a direct result." According to its memorandum, the DHHS will investigate allegations of EMTALA violations whenever it finds evidence that a newborn was not provided with at least a medical
Full Text Available Epidemiological studies and animal models suggest that early postnatal nutrition and growth can influence adult health. However, few human studies have objective recordings of early nutrient intake. We studied whether nutrient intake and growth during the first 9 weeks after preterm birth with very low birth weight (VLBW, <1500 g predict total energy intake, resting energy expenditure (REE, physical activity and food preferences in young adulthood. We collected daily nutritional intakes and weights during the initial hospital stay from hospital records for 127 unimpaired VLBW participants. At an average age 22.5 years, they completed a three-day food record and a physical activity questionnaire and underwent measurements of body composition (dual X-ray absorptiometry; n = 115 with adequate data and REE (n = 92 with adequate data. We used linear regression and path analysis to investigate associations between neonatal nutrient intake and adult outcomes. Higher energy, protein and fat intakes during the first three weeks of life predicted lower relative (=per unit lean body mass energy intake and relative REE in adulthood, independent of other pre- and neonatal factors. In path analysis, total effects of early nutrition and growth on relative energy intake were mostly explained by direct effects of early life nutrition. A path mediated by early growth reached statistical significance only for protein intake. There were no associations of neonatal intakes with physical activity or food preferences in adulthood. As a conclusion, higher intake of energy and nutrients during first three weeks of life of VLBW infants predicts energy balance after 20 years. This association is partly mediated through postnatal growth.

This study examines short-term memory, verbal working memory, episodic long-term memory, and intelligence in 32 children with mild neonatal encephalopathy (NE), 39 children with moderate NE, 10 children with NE who developed cerebral palsy (CP), and 53 comparison children, at the age of 9 to 10 years. in addition to a global effect on intelligence, NE had a specific effect on verbal working memory, verbal and visuo-spatial long-term memory, and learning, which was associated with degree of NE. Although these memory problems occurred in children without CP, they were more pronounced when children had also developed CP.

Premature birth is a significant cause of infant and child morbidity and mortality. In the United States, the premature birth rate, which had steadily increased during the 1990s and early 2000s, has decreased annually for four years and is now approximately 11.5%. Human viability, defined as gestational age at which the chance of survival is 50%, is currently approximately 23–24 weeks in developed countries. Infant girls, on average, have better outcomes than infant boys. A relatively uncomplicated course in the intensive care nursery for an extremely premature infant results in a discharge date close to the prenatal EDC. Despite technological advances and efforts of child health experts during the last generation, the extremely premature infant (less than 28 weeks gestation) and extremely low birth weight infant (ELBW) (CPAP, mechanical ventilation, and exogenous surfactant increased survival and spurred the development of neonatal intensive care in the 1970s through the early 1990s. Routine administration of antenatal steroids during premature labor improved neonatal mortality and morbidity in the late 1990s. The recognition that chronic postnatal administration of steroids to infants should be avoided may have improved outcomes in the early 2000s. Evidence from recent trials attempting to define the appropriate target for oxygen saturation in preterm infants suggests arterial oxygen saturation between 91–95% (compared to 85–89%) avoids excess mortality. However, final analyses of data from these trials have not been published, so definitive recommendations are still pending The development of neonatal neurocognitive care visits may improve neurocognitive outcomes in this high-risk group. Long-term follow up to detect and address developmental, learning, behavioral, and social problems is critical for children born at these early gestational ages. The striking similarities in response to extreme prematurity in the lung and brain imply that agents and

Nesting and positioning is a common nursing skill used in the developmental care of premature infants. This skill maintains premature infants in a comfortable position, facilitates the monitoring of stable vital signs, and enables spontaneous motor activity for normal neuromuscular and skeletal joint function. This project was designed to improve nursing staff cognition and skills regarding nesting and positioning for premature infants in the NICU. Strategies used in this project were: develop an infant position assessment tool; record a demonstration video about nesting and positioning skills to provide learning efficacy among the nursing staff; and modify an education program for new nurses. After implementation, nurse cognition regarding premature infant nesting and positioning increased from 58.3% to 92.3%. The rate of correct technique use similarly rose from 63.3% to 91.4%. This is a valid intervention for improving the correctness of nesting and positioning in nursing care. This project standardized education in terms of nesting and positioning practice goals and enhanced quality care for premature infants.
The nuclear magnetic resonance (RMN) is outlined as a progressively more accessible study. The new technology allows, even to omit the sedation of children. In the last 10 years, we have had access to the knowledge of the modifications shown by the brain of the premature newborn in growth as well as in cerebral structures. In 2003, a detailed description was published concerning the technology used to evaluate the images of premature newborns and the evolution of these images according to the own modifications of the progress during the post-conception age [es
Background Genotyping requires biological sample collection that must be reliable, convenient and acceptable for patients and clinicians. Finding the most optimal procedure of sample collection for premature neonates who have a very limited blood volume is a particular challenge. The aim of the current study was to evaluate the use of umbilical cord (UC) tissue and newborn dried blood spot (DBS)-extracted genomic DNA (gDNA) as an alternative to venous blood-derived gDNA from premature neonates for molecular genetic analysis. All samples were obtained from premature newborn infants between 24-32 weeks of gestation. Paired blood and UC samples were collected from 31 study participants. gDNA was extracted from ethylenediaminetetraacetic acid (EDTA) anticoagulant-treated blood samples (~500 μl) and newborn DBSs (n = 723) using QIAamp DNA Micro kit (Qiagen Ltd., Crawley, UK); and from UC using Qiagen DNAeasy Blood and Tissue kit (Qiagen Ltd., Crawley, UK). gDNA was quantified and purity confirmed by measuring the A260:A280 ratio. PCR amplification and pyrosequencing was carried out to determine suitability of the gDNA for molecular genetic analysis. Minor allele frequency of two unrelated single nucleotide polymorphisms (SNPs) was calculated using the entire cohort. Results Both whole blood samples and UC tissue provided good quality and yield of gDNA, which was considerably less from newborn DBS. The gDNA purity was also reduced after 3 years of storage of the newborn DBS. PCR amplification of three unrelated genes resulted in clear products in all whole blood and UC samples and 86%-100% of newborn DBS. Genotyping using pyrosequencing showed 100% concordance in the paired UC and whole blood samples. Minor allele frequencies of the two SNPs indicated that no maternal gDNA contamination occurred in the genotyping of the UC samples. Conclusions gDNAs from all three sources are suitable for standard PCR and pyrosequencing assays. Given that UC provide good quality

The goal was to evaluate whether there was neurodevelopmental deficits in newborns born to mothers with gestational diabetes mellitus (GDM) compared to control newborns born to healthy mothers. Forty-six pregnant women (21 controls and 25 GDM) were recruited. Electroencephalogram (EEG) was recorded in the newborns within 48 h after birth. The EEG signal was quantitatively analyzed using power spectral density (PSD); coherence between hemispheres was calculated in paired channels of frontal, temporal, central and occipital regions. The left centro-occipital PSD in control newborns was 12% higher than in GDM newborns (p = 0.036) but was not significant after adjustment for gestational age. While coherence was higher in the frontal regions compared to the occipital regions (p gestational age and less by GDM status of the mothers. However, there is a need to confirm this result with a higher number of mother-newborns. Quantitative EEG in GDM newborns within 48 h after birth is feasible. This study emphasizes the importance of controlling blood glucose during GDM to protect infant brain development. Copyright © 2018 ISDN. Published by Elsevier Ltd. All rights reserved.

Medulla oblongata dysplasia is an extremely rare form of neurodevelopmental immaturity in premature infants. Intracranial hemorrhage in premature infants may be closely related to neurodevelopmental immaturity. We report a female premature infant who succumbed to intracranial hemorrhage caused by medulla oblongata dysplasia. The infant was born at 31 weeks gestation. The onset manifestation was symptomatic epilepsy associated with subependymal hemorrhage. Levetiracetam and sodium valproate were administered. During the hospitalization, hydrocephalus developed and the intracranial hemorrhage aggravated. The infant died on day 171 after birth. Early identification and prompt treatment should be emphasized. Clinicians should be aware of this condition, as it can potentially cause neonatal intracranial hemorrhage.

It is unclear what the predictive value of very early development of gestures and language is on later language ability in prematurely born very-low-birth-weight (VLBW; birth weight ≤1500g) children. The aim of the present study was to analyse the predictive value of early gestures and a receptive lexicon measured between the ages of 0;9 and 1;3, as well as the predictive value of receptive and expressive language ability at 2;0 for language skills at 5;0 in VLBW children. The subjects were 29 VLBW children and 28 full-term children whose language development has been followed intensively between the ages of 0;9 and 2;0 using the Finnish version of the MacArthur Developmental Inventory and the Reynell Developmental Language Scales (RDLS III). At 5;0, five selected verbal subtests of the Nepsy II test and the Boston Naming Test (BNT) were used to assess children's language skills. For the first time in VLBW children, the development of gestures measured between the ages of 0;9 and 1;3 was shown to correlate significantly and positively with language skills at 5;0. In addition, both receptive and expressive language ability measured at 2;0 correlated significantly and positively with later language skills in both groups. Moreover, according to the hierarchical regression analysis, the receptive language score of the RDLS III at 2;0 was a clear and significant predictor for language skills at 5;0 in both groups. The findings particularly underline the role of early receptive language as a significant predictor for later language ability in VLBW children. The results provide evidence for a continuity between early language development and later language skills. After reading this article, readers will understand the associations between the very early (≤2 years of age) development of gestures and language (i.e. early receptive lexicon, expressive lexicon at 2;0, receptive and expressive language ability at 2;0) and the language skills at 5;0 in prematurely born

Lung disease represents one of the most life-threatening conditions in prematurely born children. In the evaluation of the neonatal chest, the primary and most important diagnostic study is therefore the chest radiograph. Since prematurely born children are very sensitive to radiation, those radiographs may lead to a significant radiation detriment. Hence, knowledge of the patient dose is necessary to justify the exposures. A study to assess the patient doses was started at the neonatal intensive care unit (NICU) of the Univ. Hospital in Leuven. Between September 2004 and September 2005, prematurely born babies underwent on average 10 X-ray examinations in the NICU. In this sample, the maximum was 78 X-ray examinations. For chest radiographs, the median entrance skin dose was 34 μGy and the median dose area product was 7.1 mGy.cm 2 . By means of conversion coefficients, the measured values were converted to organ doses. Organ doses were calculated for three different weight classes: extremely low birth weight infants ( 2500 g). The doses to the lungs for a single chest radiograph for infants with extremely low birth weights, low birth weights and normal birth weights were 24, 25 and 32 μGy, respectively. (authors)

Full Text Available BACKGROUND: Cerebral abscesses are extremely rare in neonates. Serratia marcescens is an unusual cause of sepsis and neurological spread is especially ominous. PURPOSE: To report the case of a 34-week neonate who developed this rare condition and to discuss diagnostic and therapeutic measures. CASE REPRT: A 34-week male neonate sequentially developed respiratory distress syndrome, early sepsis and necrotizing enterocolitis; later cultures revealed S. marcescens. After deterioration, a cerebral abscess became evident, which revealed S. marcescens. Clinical improvement ensued after high-dose amikacin and meropenem. CONCLUSION: Clinical signs are often non-specific. Proper diagnostic measures, neurosurgical consultation and aggressive antibiotic therapy are essential for these high-risk neonates.INTRODUÇÃO: Abscessos cerebrais são extremamente raros em neonatos.

Examine the relationship between delivery room resuscitation intensity and mortality, morbidities and resource use in late preterm infants. Retrospective cohort study of inborn infants born at 33 to 36 weeks' gestation and admitted to Canadian neonatal intensive care units during 2010 to 2013. The 13 619 infants were grouped according to delivery room resuscitation intensity: no or minimal resuscitation (64.5%); continuous positive airway pressure (10.2%); bag-mask ventilation (21.7%); endotracheal intubation (3.1%); and cardiopulmonary resuscitation (CPR) (0.6%). Overall mortality, early mortality, respiratory distress, pneumothorax, late-onset sepsis and resource use increased with higher intensity resuscitation. Compared with no or minimal resuscitation, intubation and CPR were associated with increased odds of mortality (adjusted odds ratio (95% confidence interval): 50 (20 to 125) and 180 (63 to 518), respectively). Intubation or higher intensity delivery room resuscitation is associated with increased mortality, morbidities and resource use in late preterm infants. Extra intensive care is required for such infants, especially during the first week of life.

Diffusion tensor imaging (DTI) has been widely used to investigate the development of the neonatal and infant brain, and deviations related to various diseases or medical conditions like preterm birth. In this study, we created a probabilistic map of fiber pathways with known associated functions, on a published neonatal multimodal atlas. The pathways-of-interest include the superficial white matter (SWM) fibers just beneath the specific cytoarchitectonically defined cortical areas, which were difficult to evaluate with existing DTI analysis methods. The Jülich cytoarchitectonic atlas was applied to define cortical areas related to specific brain functions, and the Dynamic Programming (DP) method was applied to delineate the white matter pathways traversing through the SWM. Probabilistic maps were created for pathways related to motor, somatosensory, auditory, visual, and limbic functions, as well as major white matter tracts, such as the corpus callosum, the inferior fronto-occipital fasciculus, and the middle cerebellar peduncle, by delineating these structures in eleven healthy term-born neonates. In order to characterize maturation-related changes in diffusivity measures of these pathways, the probabilistic maps were then applied to DTIs of 49 healthy infants who were longitudinally scanned at three time-points, approximately five weeks apart. First, we investigated the normal developmental pattern based on 19 term-born infants. Next, we analyzed 30 preterm-born infants to identify developmental patterns related to preterm birth. Last, we investigated the difference in diffusion measures between these groups to evaluate the effects of preterm birth on the development of these functional pathways. Term-born and preterm-born infants both demonstrated a time-dependent decrease in diffusivity, indicating postnatal maturation in these pathways, with laterality seen in the corticospinal tract and the optic radiation. The comparison between term- and preterm-born

Persistent ductus arteriosus is one of the most frequent congenital heart diseases found in infants, mainly in preterms. Echocardiography is the gold standard for the diagnosis of hemodynamically significant patent ductus arteriosus (hs-PDA) in preterm neonates. A few studies have suggested that the use of a simple blood assay to detect N-terminal pro-brain natriuretic peptide (NT-proBNP) may be useful in determining the diagnosis and management of hs-PDA. No such studies have been conducted in Indonesia, although the assay kit and characteristics of the patient (gestational age and chronological age) influence the accuracy of NT-proBNP levels in determining hs-PDA. The aim of this study was to determine the association between the NT-proBNP level and the prevalence of hs-PDA in an Indonesian patient population. A cross-sectional study was conducted at Dr. Cipto Mangunkusumo Hospital. PDA was determined using echocardiography in 49 preterm neonates (gestational age groups: non-PDA, non-hsPDA, and hs-PDA. The blood NT-proBNP level was then determined in the non-hsPDA and hs-PDA groups, and between-group differences were compared. Among the 49 neonates, 33 patients had PDA, and 16 of these had hs-PDA. The results revealed a significant association between the NT-proBNP level and hs-PDA (p < 0.001).

All out born admissions and deaths were excluded. The causes of neonatal death were classified using Wigglesworth's classification.Results: The number of inborn live births during the study period was 10064 and the total number of inborn neonatal admissions was 1475. The total deaths (neonatal and post neonatal at the neonatal intensive care unit was 73 (63 inborn and 10 out born. Among the inborn, five deaths were post neonatal deaths and hence, excluded from analysis. Among the remaining inborn neonatal deaths (n=58, 34 (59% were males and 24 (41% were females. The number of neonatal admissions increased over the years during the study period from 248 to 356, while the number of deaths also increased from 10 deaths in 2006, to 20 deaths in 2009. The primary causes of neonatal deaths were prematurity and its complications 52% (n=30. Lethal congenital malformations lead to 17 (29% newborn deaths, specific diagnosis in 7 newborns (12%, and birth asphyxia in four (7% of cases.Conclusion: There was an increasing trend of neonatal admissions and deaths among inborn babies. Prematurity, with sepsis as its major complication and congenital malformations were the leading cause of neonatal mortality.

The Mediterranean diet (MD) is associated with decreased risk of metabolic syndrome and gestational diabetes due to the anti-inflammatory and antioxidative properties of its components. The aim was to investigate the potential association of MD adherence (MDA) during pregnancy by mothers delivering prematurely, with intrauterine growth as expressed by neonates' anthropometry at birth and complications of prematurity. This is a single-center, prospective, observational cohort study of 82 women who delivered preterm singletons at post conceptional age (PCA) ≤ 34 weeks and their live-born neonates. Maternal and neonatal demographic and clinical data were recorded. All mothers filled in a food frequency questionnaire, and the MDA score was calculated. Based on 50th centile of MD score, participants were classified into high-MDA and low-MDA groups. The low-MDA mothers had significantly higher pregestational BMI and rates of overweight/obesity (odd ratios (OR) 3.5) and gestational hypertension/preeclampsia (OR 3.8). Neonates in the low-MDA group had significantly higher incidence of intrauterine growth restriction (IUGR) (OR 3.3) and lower z-scores of birth weight and BMI. Regarding prematurity-related complications, the low MDA-group was more likely to develop necrotizing enterocolitis, bronchopulmonary dysplasia, and retinopathy of prematurity (OR 3.2, 1.3, and 1.6, respectively), while they were less likely to develop respiratory distress syndrome (OR 0.49), although the differences were not statistically significant. However, adjustment for confounders revealed MDA as a significant independent predictor of hypertension/preeclampsia, IUGR, birth weight z-score, necrotizing enterocolitis, and bronchopulmonary dysplasia. High MDA during pregnancy may favorably affect intrauterine growth and certain acute and chronic complications of prematurity as well as maternal hypertension/preeclampsia.

To study the demographic and clinical features of Retinopathy of Prematurity in urban Punjab. The cross-sectional study was performed at Hameed Latif Hospital, Lahore, from April 2010 to October 2013 and comprised neonates born with birth weight less than 2000 g, gestational age less than 37 weeks, or those who were considered high risk for Retinopathy of Prematurity. Variables recorded included history, birth weight, gestational age, oxygen supplementation, development of Retinopathy of Prematurity, and laser treatment. Data was analysed using SPSS 17. There were 285 neonates in the study with a mean birth weight of 1280.34 ± 350.43 g and mean gestational age being 29.38 ± 3.14 weeks. Overall, 167 (58.6%) received supplemental oxygen, 86(30.2%) were anaemic and 44 (15.4%) received blood transfusion. Besides, 47 (16.5%) premature babies were product of multiple gestation, 34 (11.9%) were having respiratory distress, 25 (8.8%) had sepsis and received intravenous antibiotics, 70(24.6%) developed Retinopathy of Prematurity, and 22 (7.7%) developed threshold disease and received laser treatment at mean gestational age of 32.11 ± 2.53 weeks. Screening is key to preventing childhood blindness caused by Retinopathy of Prematurity. Prematurity, low birth weight and supplemental oxygen therapy are significant risk factors for the condition.
In the past 17 years neonatal mortality survey has provided important data on the trends in deaths of all live born infants born in Southern Ireland who are greater than 500 g birth weight and who die within the first 28 days of life. The aims of this study were to report neonatal mortality data for Southern Ireland for 2004, to examine trends in neonatal mortality over the past 17 years and compare Irish Neonatal Mortality rates to other countries around the world. The neonatal mortality rate for 2004 was 2.9\\/1000 with a corrected NMR of 1.9\\/1000. The response rate to the survey was 100%. Prematurity is now the leading cause of neonatal mortality representing a change from previous years. Deaths related to asphyxia have remained largely unchanged. When compared to international figures Ireland compares favourably to other countries around the world.
Full Text Available Background Rhesus incompatibility is a preventable cause for severe neonatal hyperbilirubinemia, hydrops fetalis and still births. The prevalence of the Rh-negative blood group among Indian woman varies from 2% - 10%. Despite declining the incidence of Rhesus incompatibility, due to availability of anti-D immunoglobulin, and improved antenatal care of the Rh-negative pregnant woman, it still accounts for a significant proportion of neonatal hyperbilirubinemia and neuro-morbidity. The prevalence of Rh-negative women having Rh-positive neonates is 60%. Objectives This study aimed to estimate the incidence of Rh iso-immunization and evaluate the outcomes of Rh iso-immunized neonates. Methods This prospective observational study was conducted in a tertiary level neonatal intensive care unit, Princess Esra hospital, Deccan college of medical sciences, Hyderabad, Telangana, India. Consecutive intramural and extramural neonates admitted to neonatal intensive care unit with the Rh-negative mother’s blood group and hyperbilirubinemia were enrolled. Neonates born to Rh+ve mothers were excluded. Neonatal gestational age, birth weight, age at admission, duration of phototherapy, duration of hospitalization, neonatal examination and investigations were recorded in a predesigned, pretested performa. Results A total of 90 neonates were born to Rh-negative mothers, of which 70% (63 had the Rh-positive blood group and 30% had the Rh-negative blood group. Of these 63 neonates, 48 (76.2% had hyperbilirubinemia and 43 neonates (68.3% had significant hyperbilirubinemia (total serum bilirubin > 15mg/dL. Among them, 2%, 75% and 23% were born to primi, multi and grandmutli, respectively. Also, 14.5% of the neonates were large for dates (LFD, 75% appropriate for dates (AFD and 10.5% were small for dates (SFD. Premature and SFD neonates had higher incidence of hyperbilirubinemia. Significantly higher incidence of jaundice occurred within 72 hours of life. The mean

To describe survival rate after preterm premature rupture of membranes (PPROM) before 25 weeks of gestation and compare neonatal morbidity and mortality among those born alive with a control group of infants born at a similar gestational age without premature rupture of membranes. We conducted a retrospective single-centre study at Port-Royal maternity, from 2007 to 2015, comparing neonatal outcomes between liveborninfants exposed to PPROM prior to 25 weeks of gestation (WG) and a control group not exposed to premature rupture of the membranes. For each live-born child, the next child born after spontaneous labor without PPROM was matched for gestational age at birth, sex, and whether or not they received antenatal corticosteroid therapy. The primary endpoint was severe neonatal complications assessed by a composite endpoint including neonatal deaths, grade 3-4 HIV, bronchopulmonary dysplasia, leukomalacia and stade 3-4 retinopathies. Among 77 cases of very premature rupture of the membranes, 55 children were born alive. Among these, the average gestational age at birth was 28 WG and 1 day. The rate of severe neonatal complications did not differ between the two groups (43.6% in the PPROM group vs. 36.4%, P=0.44) and the survival rate at discharge was also similar in the two groups (85.5% vs. 83.6%, P=0.98). In our cohort and among livebirths after 24 WG, PPROM before 25 WG was not associated with an increased risk of morbidity and mortality compared to children born at the same gestational age after a spontaneous labor with intact membranes.

Prematurity and low birth weight have been exclusion criteria for extracorporeal membrane oxygenation (ECMO); however, these criteria are not evidence based. With advances in anticoagulation, improved technology, and surgical expertise, it is difficult to deny a potential therapy based on these criteria alone. We report the outcome of three neonates who were ineligible based on traditional criteria but were offered ECMO as a life-saving measure. We highlight the interdisciplinary nature of modern decision-making. All three neonates had severe congenital diaphragmatic hernia diagnosed prenatally, had normal fetal karyotypes, were born prematurely, and weighed less than 2 kg. All three neonates underwent cervical venoarterial cannulation, stabilization on ECMO, and repair of their congenital diaphragmatic hernia early in their ECMO courses. All three infants had long courses of respiratory support attributable to lung hypoplasia, but there were no short- or long-term complications attributable to ECMO support directly. All three are alive at 2 years of age and were making progress developmentally. In conclusion, with interdisciplinary collaboration and clinical guidelines uniformly implemented, low birth weight infants may benefit from ECMO and should not be denied the therapy arbitrarily based on gestational age or size alone. Further research is essential to determine appropriate patient selection in premature infants.

We assessed the hematopoietic stem and progenitor cell (HSPC) population in the cord blood of neonates born to mothers with gestational diabetes mellitus (GDM) in a hypothesis generating pilot study, due to that, neonatal polycythemia may be the consequence of GDM pregnancy. Forty-five pregnant women with GDM (last trimester mean HbA1C = 33.9 mmol/mol) and 42 (nondiabetic) control pregnant women were enrolled after their routine 75 g oral glucose tolerance test (OGTT) between the 24th and 28th gestational week (with expected differences in their mean routine clinical characteristics: plasma glucose at OGTT: 0' = 5.07 vs. 4.62 mM, 120' = 8.9 vs. 5.76 mM, age = 35.07 vs. 31.66 years, prepregnancy body mass index = 27.9 vs. 23.9 kg/m(2), GDM vs. control, respectively) on a voluntary basis after signing the informed consent. EDTA-treated cord blood samples were analyzed by flow cytometry and the software Kaluza1.2 using CD45 and CD34-specific fluorescent antibodies to identify the HSPC population (CD34(+) cells within the CD45(dim) blast gate). The proportion of CD34(+)CD45(dim) HSPCs among the nucleated cells was significantly (P mothers with GDM (median 0.38%) compared to neonates born to nondiabetic mothers (median 0.32%) and according to treatment types (P cells in the cord blood may possibly be related to altered fetal stem cell mobilization in GDM pregnancy, yet these results should be interpreted only as preliminary due to the small sample sizes.

The long-term consequences of extreme prematurity are becoming increasingly important, given recent improvements in neonatal intensive care. The aim of the current study was to examine the cardiovascular consequences of extreme prematurity in 11-year-olds born at or before 25 completed weeks of gestation. Age and sex-matched classmates were recruited as controls. Information concerning perinatal and maternal history was collected, and current anthropometric characteristics were measured in 219 children born extremely preterm and 153 classmates. A subset of the extremely preterm children (n = 68) and classmates (n = 90) then underwent detailed haemodynamic investigations, including measurement of supine blood pressure (BP), aortic pulse wave velocity (aPWV, a measure of aortic stiffness) and augmentation index (AIx, a measure of arterial pressure wave reflections). Seated brachial systolic and diastolic BP were not different between extremely preterm children and classmates (P = 0.3 for both), although there was a small, significant elevation in supine mean and diastolic BP in the extremely preterm children (P prematurity is associated with altered arterial haemodynamics in children, not evident from the examination of brachial BP alone. Moreover, the smaller, preresistance and resistance vessels rather than large elastic arteries appear to be most affected. Children born extremely preterm may be at increased future cardiovascular risk.
Full Text Available A sample of 51 children aged 7 with a history of prematurity was compared to 44 age-matched children who were born at term at the HCPA. The premature children had had gestational ages up to 37 weeks and 6 days and were born weighing less than 2500g. The control group consisted of children born with gestational age between 38 and 42 weeks and weights above 2S00g. The evaluation criteria were clinical examination, neurological examination and the evolutional neurological evaluation (ENE. The results pointed out that impulsiveness, aggressiveness, disorganization and enuresis were prevalent symptoms of developmental disturbances in the sample of prematures. Alterations at neurological examination did not discriminate between the two groups, although cerebral palsy occurred only in the proup of prematures. The ENE functions which differentiated the two groups studied were dynamic balance, appendicular and trunk-limb coordination and motor persistence.Para estudar o desenvolvimento neuropsicomotor em amostra de prematuros aos 7 anos de idade, foram avaliadas 51 crianças prematuras e comparadas com 44 a termo.

Full Text Available Multiple pregnancy is a pregnancy where more than one fetus develops simultaneously in the womb, as a result of the ovulation and fertilization of more than one egg. It is relatively rare in humans and represents the rest of the phylogenetic stages. The most common are twins and they indicate the development of two fetuses in the womb. The frequency of twin pregnancies is about 1%. Multiple pregnancies belong to a group of high-risk pregnancies because of the many complications that occur during the pregnancy: higher number of premature deliveries, bleeding, early neonatal complications and higher perinatal morbidity and mortality. Such pregnancies and infants require greater supervision and monitoring. The aim of this study was to determine the percentage of baby twins born at the maternity ward of the General Hospital in Prokuplje and their morbidity and mortality. Data on the total number of deliveries, number of twins, parity and maternal age, gestational age, body weight of twins, method of delivery, Apgar score and perinatal mortality were collected and statistically analyzed by means of retrospective analysis of operative birth and neonatal protocol for 6 years (2005 of 2010. Out of 4527 mothers who gave birth 43 were pairs of twins, or 0.95% of women gave birth to twins. These babies are more likely born by Caesarean section, but delivered with slightly lower birth weight.

Neonatal Graves' disease presenting as conjugated hyperbilirubinemia is a diagnostic challenge because the differential includes a gamut of liver and systemic diseases. We present a unique case of neonatal Graves' disease in a premature infant with conjugated hyperbilirubinemia born to a mother with hypothyroidism during pregnancy and remote history of Graves' disease. Infant was treated with a combination of methimazole, propranolol, and potassium iodide for 4 weeks. Thyroid function improved after 8 weeks of treatment with full recovery of thyroid function, disappearance of thyroid-stimulating antibodies, and resolution of failure to thrive and conjugated hyperbilirubinemia. This case provides several clinical vignettes as it is a rare, severe, presentation of an uncommon neonatal disease, signs, symptoms, and clinical history presented a diagnostic challenge for neonatologists and endocrinologists, normal newborn screen was misleading, and yet timely treatment led to a full recovery.

Lung disease represents one of the most life-threatening conditions in prematurely born children. In the evaluation of the neonatal chest, the primary and most important diagnostic study is the chest radiograph. Since prematurely born children are very sensitive to radiation, those radiographs may lead to a significant radiation detriment. Knowledge of the radiation dose is therefore necessary to justify the exposures. To calculate doses in the entire body and in specific organs, computational models of the human anatomy are needed. Using medical imaging techniques, voxel phantoms have been developed to achieve a representation as close as possible to the anatomical properties. In this study two voxel phantoms, representing prematurely born babies, were created from computed tomography- and magnetic resonance images: Phantom 1 (1910 g) and Phantom 2 (590 g). The two voxel phantoms were used in Monte Carlo calculations (MCNPX) to assess organ doses. The results were compared with the commercially available software package PCXMC in which the available mathematical phantoms can be downsized toward the prematurely born baby. The simple phantom-scaling method used in PCXMC seems to be sufficient to calculate doses for organs within the radiation field. However, one should be careful in specifying the irradiation geometry. Doses in organs that are wholly or partially outside the primary radiation field depend critically on the irradiation conditions and the phantom model

This study aims to describe the impact of twin birth, chorionicity, intertwin birth weight (BW) discordance and birth order on neonatal outcomes. We performed a hospital-based retrospective study on 2,170 twins (6.4% of all live births) and 2,217 singletons inborn 2007 to 2011. Data on neonatal characteristics, morbidities, and mortality were collected and compared. Univariate and multiple (adjusted for gestational age [GA] and gender) linear random intercept regression models were used. Overall, 62.3% of twins were born premature. At multiple regression, twins were similar to singletons for neonatal morbidities, but they were more likely to have lower BW and to be born by cesarean delivery. Monochorionic twins had lower GA and BW compared with dichorionic ones and were more likely to develop respiratory distress syndrome (odds ratio [OR], 1.7), hypoglycemia (OR, 3.3), need for transfusion, (OR, 3.4) but not brain abnormalities. Moderate and severe BW discordance were associated with longer length of stay and increased risk for morbidities but not for death. Birth order had no effects. Prematurity was the most common outcome in twins and accounted for the apparently increased risk in morbidities. Monochorionicity was confirmed as risk factor for lower GA and neonatal morbidities. BW discordance may play a role in developing neonatal complications and needs to be further investigated. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

Animal studies have shown that corticosteroids (dexamethasone) cause neuronal loss in the hippocampus and deficits in short term memory. Proton magnetic resonance spectroscopy can measure brain metabolites in vivo and give an indication of neuronal integrity. We investigated whether prolonged administration of hydrocortisone during the neonatal period for bronchopulmonary dysplasia (BPD) in preterm born children changes the metabolism in the hippocampus, measured at school age. Secondly, we investigated whether hippocampal metabolism and short-term memory and neurodevelopmental outcome are related. In this observational study 37 preterm born children (children were treated with hydrocortisone for BPD (starting dose 5 mg/kg/d tapered over a minimum period of 22 d, median duration 28 d) and 19 never received corticosteroids during the perinatal period. N-acetyl aspartate/ Choline + Creatine/phosphocreatine (NAA/(Cho + Cr)) ratios were determined. A 15-word recall memory test and an IQ measurement were obtained on the same day. Hydrocortisone treated children were younger, lighter and sicker than their nonsteroid treated counterparts. Mean NAA/(Cho + Cr) ratios in the hippocampus were not significantly different in the hydrocortisone group compared with the non-steroid group. Performance on the 15-word memory test and IQ were similar in the two groups. There was no relation between NAA/(Cho + Cr) ratios and memory nor between NAA/(Cho + Cr) ratios and IQ. We conclude that hydrocortisone in the mentioned dose, administered in the neonatal period for BPD, does not appear to have any long-term effects on memory and/or hippocampal metabolism.

Full Text Available Abstract Introduction Resistance to thyroid hormone is a syndrome caused by thyroid hormone receptor β mutations, which are usually inherited in an autosomal-dominant pattern. Case presentation Our patient, a Japanese neonate boy, showed hyperthyroid symptoms at age two days. Although our patient was diagnosed as having resistance to thyroid hormone, his hyperthyroid symptoms continued for two weeks. Therefore, our patient was treated with methimazole and iodine for two weeks from birth, showing no side effects and no symptoms upon treatment. At age 70 days, an R243W mutation in thyroid hormone receptor β was detected in our patient; while absent in his mother, the mutation was present in his father, who never showed any symptoms. Conclusions To the best of our knowledge this is the first case report of a resistance to thyroid hormone in a neonate presenting with hyperthyroid symptoms born to a mother with Graves’ disease and treated with methimazole and iodine. These results suggest that methimazole and iodine may be a good short-term option for treatment.

Retinopathy of prematurity has been the leading cause of childhood blindness. Early and effective screening has helped to diagnose the visual target of an infant by the difference between growing up with a disability or not. A joint effort between ophthalmologists and neonatologists is proposed to control this disease, ensuring success. An appropriate, early, effective and timely treatment has been the laser and cryotherapy like good choices for the neonate to prevent disease progression. Evaluation of screening program, to determine the incidence, compare statistics variables have been measures as other medical pathologies should be encouraged as research topics. A decrease in the incidence of retinopathy of prematurity is expected, controlling the risk factors during the child's stay in intrahospital neonatal unit [es

Premature menopause affects 1% of women under the age of 40 years. The women are at risk of premature death, neurological diseases, psychosexual dysfunction, mood disorders, osteoporosis, ischemic heart disease and infertility. There is need to use simplified protocols and improved techniques in oocyte donation to achieve pregnancy and mother a baby in those women at risk. Review of the pertinent literature on premature menopause, selected references, internet services using the PubMed and Medline databases were included in this review. In the past, pregnancy in women with premature menopause was rare but with recent advancement in oocyte donation, women with premature menopause now have hoped to mother a child. Hormone replacement therapy is beneficial to adverse consequences of premature menopause. Women with premature menopause are at risk of premature death, neurological diseases, psychosexual dysfunction, mood disorders, osteoporosis, ischemic heart disease and infertility. Public enlightenment and education is important tool to save those at risk.

The factors that contribute to the development of acute kidney injury (AKI) and treatment outcome among prematurely born neonates are not clearly understood. This retrospective study included 150 prematurely born neonates. AKI was defined as an increase of serum creatinine levels ≥0.3 mg/dl compared to basal values. The majority of neonates with AKI (94.8 %) had a body weight 5 on the first day of life, core body temperature hemorrhage, necrotizing enterocolitis, patent ductus arteriosus, as well as a treatment with vancomycin or dopamine were independent risk factors for the development of AKI. After the groups of neonates with and without AKI were adjusted, the calculated risk ratio for a negative outcome of treatment (death) was 2.215 (CI 1.27-3.86) for neonates with AKI. Neonates with AKI had higher serum sodium levels in the third and fourth days of life. AKI is associated with high mortality in preterm neonates. It is very important to identify, as quickly as possible, all infants who are at high risk of developing AKI.
Full Text Available Abstract Background The aim of this study, conducted in Europe, was to develop a validated risk factor based model to predict RSV-related hospitalisation in premature infants born 33–35 weeks' gestational age (GA. Methods The predictive model was developed using risk factors captured in the Spanish FLIP dataset, a case-control study of 183 premature infants born between 33–35 weeks' GA who were hospitalised with RSV, and 371 age-matched controls. The model was validated internally by 100-fold bootstrapping. Discriminant function analysis was used to analyse combinations of risk factors to predict RSV hospitalisation. Successive models were chosen that had the highest probability for discriminating between hospitalised and non-hospitalised infants. Receiver operating characteristic (ROC curves were plotted. Results An initial 15 variable model was produced with a discriminant function of 72% and an area under the ROC curve of 0.795. A step-wise reduction exercise, alongside recalculations of some variables, produced a final model consisting of 7 variables: birth ± 10 weeks of start of season, birth weight, breast feeding for ≤ 2 months, siblings ≥ 2 years, family members with atopy, family members with wheeze, and gender. The discrimination of this model was 71% and the area under the ROC curve was 0.791. At the 0.75 sensitivity intercept, the false positive fraction was 0.33. The 100-fold bootstrapping resulted in a mean discriminant function of 72% (standard deviation: 2.18 and a median area under the ROC curve of 0.785 (range: 0.768–0.790, indicating a good internal validation. The calculated NNT for intervention to treat all at risk patients with a 75% level of protection was 11.7 (95% confidence interval: 9.5–13.6. Conclusion A robust model based on seven risk factors was developed, which is able to predict which premature infants born between 33–35 weeks' GA are at highest risk of hospitalisation from RSV. The model could be

Brain immaturity at birth poses critical neurological risks in the preterm-born infants. We used a novel change-point model to analyze the critical gestational age at birth (GAB that could affect postnatal development, based on diffusion tensor MRI (DTI acquired from 43 preterm and 43 term-born infants in 126 brain regions. In the corresponding research article, we presented change-point analysis of fractional anisotropy (FA and mean diffusivities (MD measurements in these infants. In this article, we offered the relative changes of axonal and radial diffusivities (AD and RD in relation to the change of FA and FA-based change-points, and we also provided the AD- and RD-based change-point results.

Retinopathy of prematurity is an avoidable cause of childhood blindness. Proper understanding of the classification and treatment methods is a must in tackling this disease. Literature search with PubMed was conducted covering the period 1940-2015 with regards to retinopathy of prematurity, retrolental fibroplasia, its natural history, classification and treatment. The clinical features, screening and staging of retinopathy of prematurity according to International classification of retinopathy of prematurity (ICROP) has been included with illustrations. The standard current treatment indications, modalities and outcomes from landmark randomized controlled trials on retinopathy of prematurity have been mentioned. This review would help pediatricians to update their current knowledge on classification and treatment of retinopathy of prematurity. Screening for retinopathy of prematurity, in India, should be performed in all preterm neonates who are born <34 weeks gestation and/or <1750 grams birthweight; as well as in babies 34-36 weeks gestation or 1750-2000 grams birthweight if they have risk factors for ROP. Screening should start by one month after birth.

Full Text Available Abstract Background Despite the significant reduction in childhood mortality, neonatal mortality has shown little or no concomitant decline worldwide. The dilemma arises in that the lack of documentation of cause of death in developing countries, where registration of vital events is virtually nonexistent. Understanding of the causes of death in neonates is important to guide public health interventions. The present study identifies the common causes of neonatal death in Ethiopia. Methods A prospective cohort study was conducted among neonates born between April 2014 and July 2014 in seven hospitals, in Tigray region, Ethiopia. Mothers were interviewed by midwifes respecting risk factors and infant survival. For neonates who died in hospital, causes of death were extracted from medical records, whereas a verbal autopsy method provided presumptive assignment of cause of death for those infants who died at home. Results Of the1152 live births, there were 68 deaths (63 per 1000 live births. Two thirds of deaths were attributable to prematurity 23 (34% or asphyxia 21 (31%. Slight variance was seen between the morality patterns in early and late neonatal periods. In the early neonatal period, 37% were due to prematurity, while asphyxia (35% was more common in the late neonatal period. All infection-related deaths occurred in neonate-mother dyads from rural areas. Conclusion Prematurity, asphyxia, and infections were the leading causes of neonatal deaths in Tigray region during the study period. Causes of deaths identified during early and late neonatal mortality differed, which clearly indicates the need for responsive and evidence-based interventions and policies.

This study assessed the risk for maternal complications in women and neonatal outcomes in children conceived following assisted reproductive treatment as compared with spontaneously conception and also separately evaluated conventional IVF and intracytoplasmic sperm injection (ICSI). The prospective cohort included 1161 women with singleton pregnancies: 561 who conceived following assisted reproduction (223 following IVF and 338 following ICSI) and 600 who conceived spontaneously. No differences were observed in pregnancy complications (including spontaneous abortion, pregnancy-induced hypertension, gestational diabetes and Caesarean delivery) except for significantly increased risk for excess vaginal bleeding in assisted reproduction pregnancies (21.4% versus 12.9%; OR 1.67, 95% CI 1.18-2.37), which was prominent in women who reported polycystic ovary syndrome. Neonates born following assisted reproduction had increased risk for prematurity (10.6% versus 5.3%; OR 1.72, 95% CI 1.04-2.87), and IVF, but not ICSI, was associated with significantly increased risk for prematurity (OR 2.36, 95% CI 1.28-4.37) and low birthweight (OR 1.89, 95% CI 1.03-3.46). In conclusion, this study observed only an increased risk for excess vaginal bleeding as a pregnancy-associated complication in singleton pregnancies following assisted compared with spontaneous conception. However, singleton neonates born following IVF, but not ICSI, were at increased risk for prematurity. Copyright © 2013 Reproductive Healthcare Ltd. Published by Elsevier Ltd. All rights reserved.

Ficolins and one collectin, mannan-binding lectin (MBL), are the only factors known to activate the lectin pathway (LP) of complement. There is considerable circumstantial evidence that MBL insufficiency can increase susceptibility to various infections and influence the course of several non-infectious diseases complicated by infections. Much less information is available concerning l-ficolin. We report the results of a prospective study to investigate any association between either MBL deficiency or l-ficolin deficiency with prematurity, low birthweight or perinatal infections in a large cohort of Polish neonates, representing an ethnically homogenous population (n=1832). Cord blood samples were analysed to determine mbl-2 gene variants, MBL concentrations and MBL-MASP-2 complex activities (MBL-dependent lectin pathway activity) as well as l-ficolin levels. Median concentrations of l-ficolin and MBL were 2500 and 1124 ng/ml, respectively, while median LP activity was 272 mU/ml. After genotyping, 60.6% of babies were mbl-2 A/A, 35.4% were A/O and 4% were O/O genotypes. We found relative l-ficolin deficiency to be associated with prematurity, low birthweight and infections. l-Ficolin concentration correlated with gestational age and with birthweight, independently of gestational age. Preterm deliveries (prematurity. Our findings suggest that l-ficolin participates in host defence during the perinatal period and constitute the first evidence that relative l-ficolin deficiency may contribute to the adverse consequences of prematurity. Some similar trends were found with facets of MBL deficiency, but the observed relationships were weaker and less consistent.

Pregnancies after kidney transplantation are at high risk of complications such as preterm birth and foetal growth restriction. Until now, the impact of these factors on neurological development of children born to transplant mothers has not been established. A comparison of neurological examinations performed in 36 children of kidney transplant women (study group) and 36 children born to healthy mothers (control group). The children from both groups were born at a similar gestational age and in the similar time period from 12/1996 to 09/2012. Neurological examinations were performed from 07/2010 to 11/2013. Each examination was adjusted to the patient's age and performed after the neonatal period. Three years later children were re-consulted, if they presented neurological deviations or were less than 12 months old at the time of the first examination. Normal neurological development was found in 86% of children in both groups (p = .999). Mild neurological deviations were observed in four (11%) children born to kidney transplant mothers and in five (14%) children born to healthy mothers (p = .999). Moderate deviations were diagnosed in one premature child born to transplant mother, whose pregnancy was complicated with a severe preeclampsia and foetal growth restriction. In the study population, no severe neurological disorders were found. Almost all (8/10) children with neurological deviations were born prematurely in good general conditions. The neurological deviations observed in the first year of life were mild and transient. In children over 1 year of age, deviations were more pronounced and continued to maintain. The neurological development of children of kidney transplant women is similar to that of the general population and possible deviations seem to be the result of intrauterine hypotrophy and prematurity. Therefore, in clinical practice, it is necessary to plan post-transplant pregnancies especially in women at high risk of these complications.

Objective was to estimate the incidence of major and minor congenital malformations among live born infants at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Estimation of risk factors was also evaluated. Between March 2004 and May 2005, a total of 5356 babies born at King Abdulaziz University Hospital, were enrolled in this study for malformations. Details of cases were recorded after parent's interviews, clinical, radiological and laboratory evaluations. One hundred and forty-seven (27.06/1000 livebirth) and 13 (2.39/1000 birth) stillbirth have congenital anomalies. In all livebirth, incidences of major anomalies were 93.9% and minor were 6.1%. Mothers of 95.9% with congenital malformation were healthy, 3.4% were diabetic and 0.7% had cardiac malformation. In 38.8% of cases parents were consanguineous. Among the liveborn births, the most common system involved was cardiovascular (7.1/1000), followed by musculoskeletal/limb (4.1/1000), external genitilia (2.8/1000), urinary (2.6/1000),multiple chromosomal (2.2/1000), orofacial (1.9/1000), central nervous system (1.9/1000), skin (1.7/1000), multiple single gene (1.3/1000), multiple sequence (0.75/1000), eyes (0.56/1000), unclassified (0.19/1000), musculoskeletal/abdominal (0.19/1000), endocrine (0.19/1000). High incidence of major malformation was found in Jeddah. Importance of Genetic Counseling is revealed in our study since more than three quarters of mothers were under 36 years and may well plan future pregnancies. (author)

BACKGROUND: The risk of cerebral palsy, the commonest physical disability of children in western Europe, is higher in infants of very low birthweight (VLBW)--those born weighing less than 1500 g--and those from multiple pregnancies than in infants of normal birthweight. An increasing proportion....... The frequency of cerebral palsy was higher in male than female babies in the group of birthweight 1000-1499 g (61.0 [53.8-68..2] vs 49.5 [42.8-56.2] per 1000 livebirths; p=0.0025) but not in the group of birthweight below 1000 g. INTERPRETATION: These data from a large population base provide evidence...

Full Text Available ABSTRACT INTRODUCTION: Abnormalities in auditory function of newborns may occur not only because of preterm birth, but also from the use of medications and from diseases related to prematurity. OBJECTIVE: To analyze the inhibitory effect from stimulation of the olivocochlear efferent system on transient evoked otoacoustic emissions in preterm neonates, comparing these data with those from full-term neonates. METHODS: This was a prospective, cross-sectional, contemporary cohort study with 125 neonates, pooled into two groups: full-term (72 full-term neonates, 36 females and 36 males, born at 37-41 weeks of gestational age; and preterm (53 neonates, 28 males and 25 females, born at ≤36 weeks of gestational age, evaluated at the corrected gestational age of 37-41 weeks. Otoacoustic emissions were recorded using linear and nonlinear click-evoked stimuli, with and without contralateral stimulation. RESULTS: The inhibitory effect of the efferent pathway in otoacoustic emissions was different (p = 0.012 between groups, and a mean reduction of 1.48 dB SPL in full-term births and of 1.02 dB SPL in preterm births was observed for the non-linear click-evoked stimulus. CONCLUSION: The results suggest a reduced inhibitory effect of the olivocochlear efferent system on otoacoustic emissions in preterm neonates.

To describe spontaneous hearing improvement in the first years of life of a number of preterm neonates relative to cochlear implant candidacy. Retrospective case study. Hearing levels of 14 preterm neonates (mean gestational age at birth = 29 weeks) referred after newborn hearing screening were evaluated. Initial hearing thresholds ranged from 40 to 105 dBHL (mean = 85 dBHL). Hearing level improved to normal levels for four neonates and to moderate levels for five, whereas for five neonates, no improvement in hearing thresholds was observed and cochlear implantation was recommended. Three of the four neonates in whom the hearing improved to normal levels were born prior to 28 weeks gestational age. Hearing improvement was mainly observed prior to a gestational age of 80 weeks. Delayed maturation of an immature auditory pathway might be an important reason for referral after newborn hearing screening in premature infants. Caution is advised regarding early cochlear implantation in preterm born infants. Audiological follow-ups until at least 80 weeks gestational age are therefore recommended. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

Full Text Available From 7% to 10% of all retinoblastomas and from 44% to 71% of familial retinoblastomas in developed countries are diagnosed in the neonatal period, usually through pre- or post-natal screening prompted by a positive family history and sometimes serendipitously during screening for retinopathy of prematurity or other reasons. In developing countries, neonatal diagnosis of retinoblastoma has been less common. Neonatal retinoblastoma generally develops from a germline mutation of RB1, the retinoblastoma gene, even when the family history is negative and is thus usually hereditary. At least one-half of infants with neonatal retinoblastoma have unilateral tumors when the diagnosis is made, typically the International Intraocular Retinoblastoma Classification (Murphree Group B or higher, but most germline mutation carriers will progress to bilateral involvement, typically Group A in the fellow eye. Neonatal leukokoria usually leads to the diagnosis in children without a family history of retinoblastoma, and a Group C tumor or higher is typical in the more advanced involved eye. Almost all infants with neonatal retinoblastoma have at least one eye with a tumor in proximity to the foveola, but the macula of the fellow eye is frequently spared. Consequently, loss of reading vision from both eyes is exceptional. A primary ectopic intracranial neuroblastic tumor known as trilateral retinoblastoma is no more common after neonatal than other retinoblastoma. For many reasons, neonatal retinoblastoma may be a challenge to eradicate, and the early age at diagnosis and relatively small tumors do not guarantee the preservation of both eyes of every involved child. Oncology nurses can be instrumental in contributing to better outcomes by ensuring that hereditary retinoblastoma survivors receive genetic counseling, by referring families of survivors to early screening programs when they are planning for a baby, and by providing psychological and practical support
Full Text Available Background: A Premature infants undergo multiple painful procedures during treatment; thus, it must be tried to limit complications caused by diagnostic and treatment procedures using simple and practical methods. This study was performed to evaluate the effect of spike lavender lakhlakhe on pain intensity due to phlebotomy in hospitalized premature infants.Methods: This single-arm, randomized clinical trial was performed on 30 infants chosen through convenience sampling method. Each newborn was considered as its own control. For the test group, one drop of pure (100% spike lavender lakhlakhe was taken by a standard dropper and diluted with 4 ml of warm distilled water by the research assistant. This mixture was stirred at 2-3 cm distance of the newborns’ nose from 60 minutes before until 2 minutes after phlebotomy, such that it could be smelled by the newborns. In both groups, heart rate and blood oxygen saturation were measured by a standard portable device, and the corresponding data was recorded in data collection sheets. Moreover, the infants’ facial expression changes were recorded by a camera and the intensity of pain was measured by Premature Infant Pain Profile before and after the procedure. Finally, the data was analyzed by paired comparison analysis test in SPSS, version 17.Results: Comparison of mean pain intensity caused by phlebotomy in the control and test groups showed a significant difference (7.667±0.311 vs. 4.882±0.311; P

: Compared with infants of mothers who were at a normal weight before pregnancy (BMI of 18.5 or more but less than 25), neonatal mortality was increased in infants of mothers who were overweight (BMI of 25 or more but less than 30) or obese (BMI of 30 or more) (adjusted hazard ratios 1.7, CI 1.2-2.5, and 1.......6, CI 1.0-2.4, respectively). For preterm infants (n=3,934, 136 deaths), neonatal mortality in infants born after preterm premature rupture of membranes (PROM) was significantly increased if they were born to an overweight or obese mother (adjusted hazard ratios 3.5, CI 1.4-8.7, and 5.7, CI 2.......2-14.8). There were no associations between high BMI and neonatal mortality in infants born after spontaneous preterm birth without preterm PROM or in infants born after induced preterm delivery.

Hypothyroxinemia in premature neonates may affect long-term neurodevelopment. This study aimed to examine the effects of hypothyroxinemia of the newborn preterm infants born at 28-36 weeks of gestational age (GA) on the neurodevelopment at 4 years of age. Prospective observational cohort study conducted in Madrid, Spain. Forty-six preterm infants were included in the study. The effects of the exposure to neonatal hypothyroxinemia on mental development were examined. Using regression analyses we found that neonatal T4 had a positive association with general cognitive index and Verbal index, and neonatal FT4 with general cognitive and Memory indexes at 4 years of age. The exposure to hypothyroxinemia during the neonatal period of late preterm infants may play role in neurodevelopmental delays. Higher T4 level means a trend to higher indexes and low T4 level means a lower neurodevelopmental indexes at 4 years of age.

To determine the role of serum insulin-like growth factor-1 levels in the development of retinopathy of prematurity, which is a major cause of childhood blindness worldwide. We prospectively studied newborn infants born at a postmenstrual age of prematurity screening and follow-up. Retinopathy of prematurity was classified according to the international classification of retinopathy of prematurity. Serum Insulin like growth factor 1 levels were measured serially in blood samples on the 1 st , 3 rd , 7 th , 21 st , and 28 th day. Among the 40 infants, 11 (27.5%) constituted the retinopathy of prematurity group and 29 comprised the non-retinopathy of prematurity group. In the retinopathy of prematurity group, the mean gestational age and birth weight was significantly lower. The demographic features of the study cohort were similar. The duration of mechanical ventilation was significantly greater in the retinopathy of prematurity group compared with the non-retinopathy of prematurity group (p=0.036). In terms of neonatal morbidities such as respiratory distress syndrome, intraventricular hemorrhage, bronchopulmonary dysplasia, patent ductus arteriosus, and necrotizing enterocolitis, no differences were detected between the groups. The mean serum insulin-like growth factor-1 levels in retinopathy of prematurity group were significantly lower than those in the non-retinopathy of prematurity group at each time point (1 st , 3 rd , 7 th , 21 st , and 28 th day of postnatal life) (p=0.001). This study demonstrated the low serum insulin-like growth factor-1 levels was associated with retinopathy of prematurity development.

Full Text Available Apnea of Prematurity (AOP is common, affecting the majority of infants born at <34 weeks gestational age. Apnea and periodic breathing are accompanied by intermittent hypoxia (IH. Animal and human studies demonstrate that IH exposure contributes to multiple pathologies, including retinopathy of prematurity (ROP, injury to sympathetic ganglia regulating cardiovascular action, impaired pancreatic islet cell and bone development, cerebellar injury, and neurodevelopmental disabilities. Current standard of care for AOP/IH includes prone positioning, positive pressure ventilation, and methylxanthine therapy; these interventions are inadequate, and not optimal for early development.The objective is to support breathing in premature infants by using a simple, non-invasive vibratory device placed over limb proprioceptor fibers, an intervention using the principle that limb movements trigger reflexive facilitation of breathing.Premature infants (23-34 wks gestational age, with clinical evidence of AOP/IH episodes were enrolled 1 week after birth. Caffeine treatment was not a reason for exclusion. Small vibration devices were placed on one hand and one foot and activated in 6 hour ON/OFF sequences for a total of 24 hours. Heart rate, respiratory rate, oxygen saturation (SpO2, and breathing pauses were continuously collected.Fewer respiratory pauses occurred during vibration periods, relative to baseline (p<0.005. Significantly fewer SpO2 declines occurred with vibration (p<0.05, relative to control periods. Significantly fewer bradycardic events occurred during vibration periods, relative to no vibration periods (p<0.05.In premature neonates, limb proprioceptive stimulation, simulating limb movement, reduces breathing pauses and IH episodes, and lowers the number of bradycardic events that accompany aberrant breathing episodes. This low-cost neuromodulatory procedure has the potential to provide a non-invasive intervention to reduce apnea, bradycardia and

Caffeine citrate therapy for apnea of prematurity reduces the rates of bronchopulmonary dysplasia, severe retinopathy, and neurodevelopmental disability at 18 months and may improve motor function at 5 years. To evaluate whether neonatal caffeine therapy is associated with improved functional outcomes 11 years later. A follow-up study was conducted at 14 academic hospitals in Canada, Australia, and the United Kingdom from May 7, 2011, to May 27, 2016, of English- or French-speaking children who had been enrolled in the randomized, placebo-controlled Caffeine for Apnea of Prematurity trial between October 11, 1999, and October 22, 2004. A total of 1202 children with birth weights of 500 to 1250 g were eligible for this study; 920 (76.5%) had adequate data for the main outcome. Caffeine citrate or placebo until drug therapy for apnea of prematurity was no longer needed. Functional impairment was a composite of poor academic performance (defined as at least 1 standard score greater than 2 SD below the mean on the Wide Range Achievement Test-4), motor impairment (defined as a percentile rank of ≤5 on the Movement Assessment Battery for Children-Second Edition), and behavior problems (defined as a Total Problem T score ≥2 SD above the mean on the Child Behavior Checklist). Among the 920 children (444 females and 476 males; median age, 11.4 years [interquartile range, 11.1-11.8 years]), the combined rates of functional impairment were not significantly different between the 457 children assigned to receive caffeine compared with the 463 children assigned to receive placebo (145 [31.7%] vs 174 [37.6%]; adjusted odds ratio, 0.78; 95% CI, 0.59-1.02; P = .07). With all available data, including those from up to 24 Swedish trial participants, the rates of poor academic performance on 1 or more of 4 subtests (66 of 458 [14.4%] vs 61 of 462 [13.2%]; adjusted odds ratio, 1.11; 95% CI, 0.77-1.61; P = .58) and behavior problems (52 of 476 [10.9%] vs 40 of 481 [8

The presence of alpha-defensins in bronchoalveolar lavage fluid (BALF) was investigated in a cohort of preterm newborns with gestational age (GA) groups: pneumonia group of nine neonates suffering from pulmonary infection (GA: 26.1 +/- 2.1 wk; birth weight: 787.4 +/- 309.9 g), with or without associated bloodstream infection, and nonpneumonia group of 15 neonates (GA: 27.7 +/- 2.0 wk; birth weight: 1019.0 +/- 319.8 g). BALF culture was positive for CONS (n = 5), Staphylococcus aureus (n = 1), and Candida spp (n = 3). BALF samples were analyzed by HPLC-electrospray Ionization-mass spectrometer. The alpha-defensins 1-4 concentration, absolute and differential white cells count were measured. Relative amounts of alpha-defensins 1-4 and the absolute number of neutrophils were found significantly higher in the pneumonia group with respect to the nonpneumonia group (p < 0.05). Moreover, positive significant correlations between the number of neutrophils and the alpha-defensins 1-3 levels were observed. In conclusion, our data show that preterm newborns, also at the lower GA, are able to produce alpha-defensins, underlining that their innate defense system is already active before the at-term delivery date.

Small vibration devices were placed on one hand and one foot and activated in 6 hour ON/OFF sequences for a total of 24 hours. Heart rate, respiratory rate, oxygen saturation (SpO2), and breathing pauses were continuously collected. Fewer respiratory pauses occurred during vibration periods, relative to baseline (papnea, bradycardia and intermittent hypoxia in premature neonates. ClinicalTrials.gov NCT02641249.

Full Text Available In Western developed countries, Listeria monocytogenes is not an uncommon pathogen in neonates. However, neonatal listeriosis has rarely been reported in Taiwan. We describe two cases collected from a single medical institute between 1990 and 2005. Case 1 was a male premature baby weighing 1558 g with a gestational age of 31 weeks whose mother had fever with chills 3 days prior to delivery. Generalized maculopapular rash was found after delivery and subtle seizure developed. Both blood and cerebrospinal fluid culture collected on the 1st day yielded L. monocytogenes. In addition, he had ventriculitis complicated with hydrocephalus. Neurologic development was normal over 1 year of follow-up after ventriculoperitoneal shunt operation. Case 2 was a 28-weeks' gestation male premature baby weighing 1180 g. Endotracheal intubation and ventilator support were provided after delivery due to respiratory distress. Blood culture yielded L. monocyto-genes. Cerebrospinal fluid showed pleocytosis but the culture was negative. Brain ultrasonography showed ventriculitis. Sudden deterioration with cyanosis and bradycardia developed on the 8th day and he died on the same day. Neonatal listeriosis is uncommon in Taiwan, but has significant mortality and morbidity. Early diagnosis of perinatal infection relies on high index of suspicion in perinatal health care professionals. [J Formos Med Assoc 2007;106(2:161-164

Approximately 5-7% of all infants are born prematurely, and birth before 37 weeks is the most common cause of neonatal mortality, morbidity and long-term disability. Premature infants are poorly equipped for life outside the womb, and oxidant stress has been implicated in the aetiology of visual impairment in these infants, who are often exposed to increased O2 concentrations and high light intensity in neonatal units. The carotenoids lutein and zeaxanthin, which give the macular area of the eye its yellow colour, are located in the retinal pigment epithelium of the eye, and are believed to play a role in protecting it against oxidative and light damage. The macular pigments are of dietary origin, and green leafy vegetables are the primary source of lutein and zeaxanthin. Lutein is one of the five most common carotenoids found in the diet. There is current interest in the macular pigment in relation to age-related macular degeneration, but these pigments may also have a protective role in the retinal pigment epithelium of the newborn infant. Little information is available on blood lutein and zeaxanthin levels in neonates. Levels of lutein in human milk are two to three times higher than those of beta-carotene, whereas their concentrations in the mothers' blood are approximately the same. Human milk is the main dietary source of lutein and zeaxanthin for infants until weaning occurs. The biochemical mechanisms which mediate the transport of the macular carotenoids into the eye are not known, but tubulin has been identified as the major carotenoid-binding protein, and may play a role in the physiology of the macula.

This exploratory study aimed to investigate associations between neonatal brain volumes and visual-motor integration (VMI) and fine motor skills in children born extremely preterm (EPT) when they reached 6½ years of age. Prospective population-based cohort study in Stockholm, Sweden, during 3 years. All children born before gestational age, 27 weeks, during 2004-2007 in Stockholm, without major morbidities and impairments, and who underwent MRI at term-equivalent age. Brain volumes were calculated using morphometric analyses in regions known to be involved in VMI and fine motor functions. VMI was assessed with The Beery-Buktenica Developmental Test of Visual-Motor Integration-sixth edition and fine motor skills were assessed with the manual dexterity subtest from the Movement Assessment Battery for Children-second edition, at 6½ years. Associations between the brain volumes and VMI and fine motor skills were evaluated using partial correlation, adjusted for total cerebral parenchyma and sex. Out of 107 children born at gestational age skills (r=0.54, P=0.01). Associations were also seen between fine motor skills and the volume of the cerebellum (r=0.42, P=0.02), brainstem (r=0.47, P=0.008) and grey matter (r=-0.38, P=0.04). Neonatal brain volumes in areas known to be involved in VMI and fine motor skills were associated with scores for these two functions when children born EPT without major brain lesions or cerebral palsy were evaluated at 6½ years of age. Establishing clear associations between early brain volume alterations and later VMI and/or fine motor skills could make early interventions possible. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Full Text Available Objective: to study the causes of acute intranatal hypoxia and reveal a relationship of placental changes to respiratory failure (RF in newborn infants. Subjects and methods. The investigation included 252 neonates with the complicated course of an early neonatal period. Their gestational age was 26 weeks to 40 weeks, birth weight varied from 850 g to 4100 g. 95.3% of the newborn infants were born with a low Apgar score and RF, which required mechanical ventilation immediately after birth. The neonatal status was clinically evaluated; the values of blood gas composition and acid-base balance were recorded; the pathogen was discharged from the tracheobronchial tree; chest X-ray survey and placental morphological examination were performed. Results. The main cause of neonatal respiratory failure is chronic intrauterine hypoxia caused by placental inflammatory changes and fetal-placental blood circulatory disorders, which gives rise to preterm delivery, cerebral hemodynamic disorders, and neonatal amniotic fluid aspiration. Bacteriological examination of tracheobronchial aspirations showed that no microflora growth occured in the majority of the newborns acute intranatal hypoxia. Enterococcus faecalis and Staphylococcus epidermidis were isolated in 12.3% and 8.7%, respectively. Growth of в-hemolytic streptococcus was observed in 2.8% of cases. The rate of microbial association specific only for rate premature infants with neonatal respiratory distress syndrome (NRDS was 4.8%. Conclusion. Placental changes causing fetal-placental circulatory disorders were ascertained to be responsible for acute intranatal and postnatal neonatal hypoxia. Placental inflammatory changes occurred in the majority of cases, as confirmed by bacteriological examinations of neonatal infants. Isolation of the varying microbial flora in infants with RF to a greater extent is, indicative of the infectious process occurring in the maternal body. Key words: acute intranatal

Full Text Available Background: Globally,it is estimated that approximately 13 million neonates are born prematurely each year. The development of the central nervous system in premature neonates continues outside of the uterus and in the environment of neonatal intensive care unit (NICU. This study aimed to evaluate the physical environment of hospital and nursery in Iran’s tertiary care centers. Methods: This cross-sectional study was conducted on a total of 23 NICUs of nine Universities of Medical Sciences, where students are trained in the neonatal fellowship course, from seven provinces of Iran, 20th July to 21th September 2015. Data analysis was performed using SPSS software, version 16, and descriptive statistics. Results: In this study, four dimensions of physical environment of hospitals and NICUs including the accessibility of NICU, the physical environment of NICU, infants’ bed space, and the sensory elements of bed spaces were evaluated. The obtained scores for each item was 41.17, 39.95, 38.83, and 39.28 out of 100, respectively. The highest mean score was 71.30 that was related to NICU temperature and ventilation considerations. The lowest mean score was 20, which was related to controlling over the movements around the infants’ beds. The total mean score of the physical environment of hospital and NICU was 39.77. Conclusion: According to the results, it is recommended to take appropriate action to develop physical space and infrastructures for neonatal care regarding developmental care along with other dimensions.

Full Text Available The status of 239 newborn infants born to mothers with hypertensive syndrome (a study group and that of 51 neonates from healthy mothers (a control group were analyzed. Neonatal mortality and morbidity rates were studied in relation to gestational age and the type and severity of hypertensive disorders. Hypertensive disorders in pregnancy were found to lead to still birth in 2,1% of cases, late miscarriage in 12,1%, prematurity in 47,7%, and intrauterine growth retardation in 27,6%. The incidence of diseases in the infants born to hypertensive mothers was 6,6 times higher than that in those from healthy mothers. The most common nosological entities among the newborn infants were intracranial hemorrhage (29,3%, respiratory distress syndrome (20,1%, hypoxic-ischemic brain damage (22,6%, polycythemia (8,4%, and hyperbihrubinemia (8,8%. Reproductive losses in hypertensive disorders accounted for 17,2% and occurred in 70,7% of cases in the early postnatal period. Severe pathology and prematurity are responsible for high neonatal morbidity and mortality rates.
In Germany almost 10 % of children are born before the end of 37th week of gestation. In at least one quarter of these cases, ascending infection of the vagina plays a causative role, particularly during the early weeks of gestation. If, in addition to the decidua, the amniotic membrane, amniotic fluid and the umbilical cord are also affected, infection not only triggers uterine contractions and premature rupture of membranes but also initiates a systemic inflammatory reaction on the part of the fetus, which can increase neonatal morbidity. Numerous studies and meta-analyses have found that antibiotic therapy prolongs pregnancy and reduces neonatal morbidity. No general benefit of antibiotic treatment was found for premature uterine contractions. But it is conceivable that a subgroup of pregnant women would benefit from antibiotic treatment. It is important to identify this subgroup of women and offer them targeted treatment. This overview summarizes the current body of evidence on antibiotic treatment for impending preterm birth and the effect on neonatal outcomes. PMID:24771902

Foetal condition and neonatal mortality of 637 prematurely born children with birth weights below 2,501 g were analysed, depending on modes of delivery, such as spontaneous birth, speculum delivery, use of forceps, manual support, and caesarean section. The clinical condition of the newborn, assessed five minutes from parturition by Apgar score 1, was found to depend primarily on birth weight rather than on the mode of delivery. The average Apgar values were lower for less mature newborns. While Apgar scores were worst for newborns after caesarean section delivery, the differences between approaches to delivery could not be statistically secured. Neonatal mortality went up, according to expectation, along with dropping birth weight. The mortality rate of premature births below 1,501 g was not affected by delivery modes. Prophylactic use of Shute forceps and speculum delivery appeared to be superior to spontaneous birth in the medium weight class, between 1,501 g and 2,000 g. Yet, not even here were the differences between clear postnatal mortality rates statistically secured. -Lowest mortality figures were recorded from spontaneous birth in the weight class between 2,001 g and 2,500 g, but significant differences were established only to speculum delivery. Premature newborns after caesarean section had poorer prospects than all variants of vaginal birth, but among the latter premature births from breech presentation were more endangered than others. Decisions as to vaginal, abdominal, spontaneous proprophylactically surgical approaches to premature deliveries should be taken for every individual case and due consideration of many factors.

HELLP syndrome is a serious hypertensive disorder of pregnancy with important neonatal problems in the newborn. The objective of this work was to determine the characteristics of these infants and its neonatal evolution. A retrospective observational study of all newborns of mothers with HELLP syndrome born in a university hospital between January 1, 2008 and December 31, 2013 was carried out. Thirty-three infants from 28 pregnancies (five twin gestations) were studied. A descriptive and comparative analysis between groups and a multivariate analysis of factors associated with mortality in the series took place. Of 33 newborns studied (2.2 newborns/1,000 infants total), two were stillbirths (6.1% of the total) and four died after birth (12.9% of live neonates) with overall perinatal mortality of 18.2%. Pregnancies in 28 infants ended before 37 weeks (84.8%) and 11 pregnancies ended before week 32 (33.3%). Seven infants weighed<1500g (four weighed <1000g). Of the 31 live births, 13 infants were in a <10th percentile weight for gestational age (41.9%), 20 needed neonatal resuscitation (64.5%) and 14 had leukopenia at birth (45.2%). In the final logistic regression, neonatal mortality was associated with extreme prematurity regardless of underweight, leukopenia and/or need for neonatal resuscitation. Children of mothers with HELLP syndrome have a high mortality associated with extreme prematurity, independent of the presence of leukopenia, low weight for gestational age and need for neonatal resuscitation.

A series of studies have been initiated implying a unique opportunity to evaluate and compare malocclusion traits, orthodontic treatment need, craniofacial morphology, mandibular function, signs and symptoms of temporomandibular disorders (TMD) and headache between extremely preterm (EPT; born before the 29th week of gestation) and very preterm (VPT; born between 29 and 32 weeks of gestation) and full-term born children. THIS THESIS WAS BASED ON FOUR STUDIES: Paper I. A systematic literature review was undertaken to answer the following questions: Does prematurity result in alterations of palatal morphology, dental occlusion, tooth-crown dimensions, tooth maturation and eruption? What role does neonatal oral intubation play in the appearance of the alterations? Are the alterations in morphology permanent or transient? The literature search spanned from January 1966 to November 2002 and was later extended to September 2008. Furthermore, a quality analysis of the methodological soundness of the studies in the review was performed. Paper II-IV. The aims were to compare EPT and VPT 8- to 10-year-old children with matched full-term controls considering: Prevalence of malocclusion traits and orthodontic treatment need (Paper II). Craniofacial morphology (Paper III). Mandibular function, signs and symptoms of TMD and headache (Paper IV). KEY FINDINGS IN PAPER I AND THE SUPPLEMENTARY SEARCH: Moderate scientific evidence existed for more malocclusion traits among premature children. Limited evidence was found for no delay in dental eruption, if corrected age was considered for the premature children. Insufficientwas considered for the premature children. Insufficient evidence was found for altered tooth-crown dimensions and permanent alteration of palatal morphology among prematurely children. Thus, further well-designed controlled studies which should also consider orthodontic treatment need, craniofacial morphology, TMD and headache are needed. KEY FINDINGS IN PAPER II

Full Text Available The objective of this study was to evaluate the prevalence of dental caries in 192 children, 96 born prematurely and 96 at full term, in a regional hospital in Brazil. Mean age at clinical examination was 40.72 months in the full-term group (G1 and 30.44 months in the premature group (G2. The children were divided in two age subgroups: 0 to 3 and 4 to 6 years. Statistical results (Student's t and Kruskal-Wallis tests showed that dmft was 0.43 for G1 and 0.01 for G2 in the 0-3 age subgroup, and 1.7 for G1 and 1.1 for G2 in the 4-6 age subgroup. Differences were significant between G1 and G2 only in the 0-3 age subgroup (p = 0.047. Caries evaluation showed that, of the 96 children in G1, 75 were caries free, while in G2, 84 did not have the disease. These differences were not significant (p = 0.088. The lower mean dmft found in the 0-3 age subgroup in G2 may be attributed to routines established by the hospital's neonatology staff, such as frequent dental visits and preventive instructions about oral habits, oral hygiene and diet. After this age, with the completion of the primary dentition, values increased and became similar between the G1 and G2 groups. Results also suggested a highly skewed distribution since most caries were found in only a small number of children.O objetivo deste estudo foi avaliar a prevalência da cárie dentária em 192 crianças, 96 nascidas prematuramente e 96 a termo, em um hospital regional no Brasil.

Full Text Available Prematurity is still an actual medical problem. Significant increase in the survival rate of premature babies is observed due to the progress in perinatal care .Usually, parents are not prepared for a premature birth, for the majority of them the hospitalization of a child in neonatal intensive care unit is a source of fear, moreover parents often blame themselves for the situation. Appearing emotions and questions require a compatible response from the therapeutic team. The most important activity in the practice of the team is emotional, informative, evaluative support.

Retinopathy of prematurity (ROP) is a proliferative retinal vascular disease affecting the premature infant with an incompletely vascularized retina. The spectrum of ophthalmological findings in ROP exists from minimal sequelae, which do not affect vision, to bilateral retinal detachment and total blindness. With the increased survival of very small infants, retinopathy of prematurity has become one of the leading causes of childhood blindness. Over the past two decades, major advances have been made in understanding the pathogenesis of ROP, to a large extent as a result of changes in clinical risk factors (oxygen and non-oxygen related) and characteristics observed in ROP cases. This article provides a literature review on the evolution in clinical characteristics, classification and treatment modalities and indications of ROP. Special attention is hereby paid to the neonatal factors influencing the development of ROP and to the necessity for everyone caring for premature babies to have a well-defined screening and treatment protocol for ROP. Such screening protocol needs to be based on a unit-specific ROP risk profile and, consequently, may vary between different European regions. Retinopathy of prematurity is an important cause of ocular morbidity and blindness in children. With better understanding of the pathogenesis, screening and treatment guidelines have changed over time and are unit specific.

The purpose of this study is to determine the incidence of retinopathy of prematurity (ROP) and the maternal/neonatal risk factors at a tertiary care hospital in Oman, compared to other countries. A retrospective analysis of premature neonates born with gestational age (GA) 24-32 weeks at Sultan Qaboos University Hospital, Oman, from January 2007 to December 2010. Maternal and neonatal in-hospital course was retrieved. The incidence of ROP was reported. Risk factors analyses were performed using univariate and multivariate statistics. A total of 171 neonates (57% males, 43% females) were included for analysis. The incidence of ROP (any stage) was 69/171 (40.4%). Infants with ROP had significantly lower GA (27.7±2 weeks) compared to non-ROP group (30.2±1.7 weeks), P < 0.001),P < 0.001) and significantly lower birth weight (BW) (948 ± 242 g in ROP group vs. 1348 ± 283 g in non-ROP group;P < 0.001). Other significant risk factors associated with ROP were: small for GA, respiratory distress syndrome, requirement for ventilation, duration of ventilation or oxygen therapy, bronchopulmonary dysplasia, hyperglycemia, late onset sepsis (clinical or proven), necrotizing enterocolitis, patent ductus arteriosus, seizures, and number of blood transfusions. There was no significant difference in maternal characteristics between the ROP and non-ROP groups except that mothers of infants with ROP were found to be significantly younger. Logistic regression analysis revealed early GA, low BW, duration of Oxygen therapy, and late-onset clinical or proven sepsis as independent risk factors. ROP is still commonly encountered in neonatal practice in Oman and other countries. Early GA, low BW, and prolonged oxygen therapy continue to be the main risk factors associated with the occurrence of ROP in our setting. In addition, an important preventable risk factor identified in our cohort includes clinical or proven late-onset sepsis.

Exposure to prenatal and early-life stress results in alterations in neural connectivity and an increased risk for neuropsychiatric disorders. In particular, alterations in amygdala connectivity have emerged as a common effect across several recent studies. However, the impact of prenatal stress exposure on the functional organization of the amygdala has yet to be explored in the prematurely-born, a population at high risk for neuropsychiatric disorders. We test the hypothesis that preterm birth and prenatal exposure to maternal stress alter functional connectivity of the amygdala using two independent cohorts. The first cohort is used to establish the effects of preterm birth and consists of 12 very preterm neonates and 25 term controls, all without prenatal stress exposure. The second is analyzed to establish the effects of prenatal stress exposure and consists of 16 extremely preterm neonates with prenatal stress exposure and 10 extremely preterm neonates with no known prenatal stress exposure. Standard resting-state functional magnetic resonance imaging and seed connectivity methods are used. When compared to term controls, very preterm neonates show significantly reduced connectivity between the amygdala and the thalamus, the hypothalamus, the brainstem, and the insula (p amygdala and the thalamus, the hypothalamus, and the peristriate cortex (p amygdala connectivity associated with preterm birth. Functional connectivity from the amygdala to other subcortical regions is decreased in preterm neonates compared to term controls. In addition, these data, for the first time, suggest that prenatal stress exposure amplifies these decreases.

Under supervision there were 139 pregnant women with application ART. 202 children (51 twins were born and 5 triplet babies, from them 83 premature infants born from multiple induced pregnancy have been analyzed. Results. The newborns examined by method ART, were distributed as follows: 22-28 weeks — 19 children; 29-32 weeks — 23; 33-36 weeks — 41. Asphyxia at birth was marked at all premature infants. Respiratory insufficiency at birth is revealed in 87,3% of cases. The most frequent pathologies in premature infants are revealed: neurologic infringements and bronchopulmonary pathology occured at all children, developmental anomaly — 33, 8%, retinopathies in premature infants — 26,5%. The mortality causes include: extreme immaturity, cerebral leukomalacia, IVN 3 degrees. Conclusion. The risk factors, premature birth at application of methods ART are revealed: aged primiparas, pharmacological influence, absence of physiological conditions of prenatal development; multifetation. The high percent of birth of children with ELBW and ULBW is revealed. RDCN with further BPD development, retinopathies in premature infants and CNS defeat is more often occured.
The hypothesis that radiation may accelerate aging phenomenon has been studied extensively, using the population of A-bomb survivors. In this paper, non-specific radiation-induced premature aging is discussed with a review of the literature. Cardiac lipofuscin, papillary fibrosis, aortic extensibility, hexamine/collagen ratio in the skin and aorta, testicular changes, giant hepatic cell nucleus, and neurofibril changes have so far been studied pathologically in the context of A-bomb radiation. Only testicular sclerosis has been found to correlate with distance from the hypocenter. Suggestive correlation was found to exist between the hexamine/collagen ratio in the skin and aorta and A-bomb radiation. Grip strength and hearing ability were decreased in the group of 100 rad and the group of 50-99 rad, respectively. The other physiological data did not definitely correlate with A-bomb radiation. Laboratory data, including erythrocyte sedimentation rate, α and β globulin levels, phytohemagglutinin reaction, T cell counts, erythrocyte glycophorin-A, the incidence of cerebral stroke, ischemic heart disease, and cataract were age-dependent and correlated with A-bomb radiation. These findings indicated that the occurrence of arteriosclerosis-related diseases, changes in immunological competence, and some pathological and physiological findings altered with advancing age, suggesting the correlation with A-bomb radiation. In general, it cannot be concluded that there is a positive correlation between A-bomb radiation and the premature aging. (N.K.) 51 refs

As neonatal chest images are frequently acquired to investigate the life-threatening lung diseases in prematurely born children, their optimisation in terms of X-ray exposure is required. The aim of this study was to investigate whether such dose-optimisation studies could be performed using a Monte Carlo computer model. More specifically, a Monte Carlo computer model was used to investigate the influence of Cu filtration on image quality and dose in neonatal chest imaging. Monte Carlo simulations were performed with the MCNPX code and used with voxel models representing prematurely born babies (590 and 1910 g). Physical image quality was derived from simulated images in terms of the signal difference-to-noise ratio and signal-to-noise ratio (SNR). To verify the simulation results, measurements were performed using the Gammex 610 Neonatal Chest Phantom, which represents a 1-2 kg neonate. A figure of merit was used to assist in evaluating the optimum balance between the image quality and the patient dose. The results show that the Monte Carlo computer model to investigate dose and image quality works well and can be used in dose-optimisation studies for real clinical practices. Furthermore, working at a specific constant incident air kerma (K a,I ), additional filtration proved to increase SNR with 30%, whereas working at a specific constant detector dose, extra Cu filtration reduces the lung dose with 25%. Optimum balance between patient dose and image quality is found to be 60 kVp (using extra filtration). (authors)

The purpose of this study was to evaluate the dose received by chest x-rays in neonatal care with thermoluminescent dosimetry and to determine the level of exposure where the quantum noise level does not affect the diagnostic image quality in order to reduce the dose to neonates. In pediatric radiology, especially the prematurely born children are highly sensitive to the radiation because of the highly mitotic state of their cells; in general, the sensitivity of a tissue to radiation is directly proportional to its rate of proliferation. The sample consisted of 208 neonatal chest x-rays of 12 neonates admitted and treated in a Neonatal Intensive Care Unit (NICU). All the neonates were preterm in the range of 28-34 weeks, with a mean of 30.8 weeks. Entrance Surface Doses (ESD) values for chest x-rays are higher than the DRL of 50 μGy proposed by the National Radiological Protection Board (NRPB). In order to reduce the dose to neonates, the optimum image quality was achieved by determining the level of ESD where level noise does not affect the diagnostic image quality. The optimum ESD was estimated for additional 20 chest x-rays increasing kVp and reducing mAs until quantum noise affects image quality. Copyright © 2012 Elsevier Ltd. All rights reserved.

Full Text Available This study compared the results of neurodevelopmental examination at 6 months' corrected age of premature infants with neonatal seizures and/or intracranial hemorrhage and normal premature infants. There was a statistically significant correlation (p=0.000007 between intracranial hemorrhage and seizures in the group of 68 premature infants seen in the neurodevelopmental outpatient service at Hospital de Clínicas de Porto Alegre, Brazil. Intracranial hemorrhage was significantly associated with multiparity (p=0.02. The neurodevelopmental examination at 6 months' corrected age revealed that patients who suffered neonatal intracranial hemorrhage and/or seizures had inappropriate muscle tone, strength and reflexes, as well as delay in head control. Conclusion: we compared the results of neurodevelopmental examinations of two groups of premature infants at 6 months' corrected age. The difference in neurological development at 6 months' corrected age was statistically significant when comparison was corrected for premature infants who had neonatal seizures and periventricular hemorrhage.Este estudo comparou os resultados do exame do desenvolvimento neuropsicomotor aos seis meses de idade corrigida de lactentes prematuros com crises neonatais e/ou hemorragia intracraniana com lactentes prematuros sem estas intercorrências.

Transfontanelle ultrasound imaging (TFUSI) is a routine diagnostic brain imaging method in infants who are born prematurely, whose skull bones have not completely fused together and have openings between them, so-called fontanelles. Open fontanelles in neonates provide acoustic windows, allowing the ultrasound beam to freely pass through. TFUSI is used to rule out neurological complications of premature birth including subarachnoid hemorrhage (SAH), intraventricular (IVH), subependimal (SEPH), subdural (SDH) or intracerebral (ICH) hemorrhages, as well as hypoxic brain injuries. TFUSI is widely used in the clinic owing to its low cost, safety, accessibility, and noninvasive nature. Nevertheless, the accuracy of TFUSI is limited. To address several limitations of current clinical imaging modalities, we develop a novel transfontanelle photoacoustic imaging (TFPAI) probe, which, for the first time, should allow for non-invasive structural and functional imaging of the infant brain. In this study, we test the feasibility of TFPAI for detection of experimentally-induced intra ventricular and Intraparenchymal hemorrhage phantoms in a sheep model with a surgically-induced cranial window which will serve as a model of neonatal fontanelle. This study is towards using the probe we develop for bedside monitoring of neonates with various disease conditions and complications affecting brain perfusion and oxygenation, including apnea, asphyxia, as well as for detection of various types of intracranial hemorrhages (SAH, IVH, SEPH, SDH, ICH).

Conclusion: ICSI outcomes, pregnancy outcome, neonatal outcome, and congenital malformation rate appear not to be affected by the duration of the period of cryostorage. An earlier start of the ICSI cycle following the testicular sperm cryopreservation is preferable because longer preservation is associated with more advanced maternal age.

A multidisciplinary committee composed of a panel of experts, including a member of the American Academy of Pediatrics and American Institute of Architects, has suggested that the delivery room (DR) and the neonatal intensive care units (NICU) room should be directly interconnected. We aimed to investigate the impact of the architectural design of the DR and the NICU on neonatal outcome. Two cohorts of preterm neonates born at architectural renovation of the DR realized in accordance with specific standards (Cohort 2: "new concept of DR"). In Cohort 1, neonates were initially cared for a conventional resuscitation area, situated in the DR, and then transferred to the NICU, located on a separate floor of the same hospital. In Cohort 2 neonates were assisted at birth directly in the NICU room, which was directly connected to the DR via a pass-through door. The primary outcome of the study was morbidity, defined by the proportion of neonates with at least one complication of prematurity (i.e., late-onset sepsis, patent ductus arteriosus, intraventricular hemorrhage, periventricular leukomalacia, bronchopulmonary dysplasia, retinopathy of prematurity and necrotizing enterocolitis). Secondary outcomes were mortality and duration of hospitalization. Statistical analysis was performed using standard methods by SPSS software. We enrolled 106 neonates (56 in Cohort 1 and 50 in Cohort 2). The main clinical and demographic characteristics of the 2 cohorts were similar. Moderate hypothermia (body temperature ≤ 35.9 °C) was more frequent in Cohort 1 (57%) compared with Cohort 2 (24%, p = 0.001). Morbidity was increased in Cohort 1 (73%) compared with Cohort 2 (44%, p = 0.002). No statistically significant differences in mortality and median duration of hospitalization were observed between the 2 cohorts of the study. If realized according to the proposed architectural standards, renovation of DR and NICU may represent an opportunity to reduce morbidity in preterm neonates.

Three premature infants observed to develop severe stage III retinopathy of prematurity (ROP) at 3 to 5 weeks of age received immediate treatment by cryoablation and photocoagulation, with good results. The critical importance of the ophthalmic examination of premature babies from the age of 2 weeks, so as not to overlook such cases of 'rush' type ROP is stressed and the difficulty involved in treating such small neonates is discussed.
Conclusion: Neonatal serum leptin concentrations within 24 hours of birth correlated with maternal body weight and BMI, especially in premature newborns. Premature newborns had significantly lower leptin levels than full-term newborns.
Full Text Available According to the World Health Organization, the incidence of hearing impairment in newborn population is 1-3 per 1000 (WHO, 2012. Apart from that, many authors have found that the incidence of hearing impairment is twenty times higher, 2-4%, in neonatal intensive care unit (NICU. Thus, a congenital hearing loss is the most frequent sensory or motor deficit that could be diagnosed immediately upon birth. The objective of this study was to determine the incidence of risk factors for hearing impairment in the population of preterm babies. We were especially interested in the impact of gestational age at birth on the incidence of risk factors for hearing loss. A cohort of 150 preterm babies was enrolled in the study. They were hospitalized in the Institute for Neonatology in Belgrade during 2014 and 2015 and the data were obtained from their medical files. The results of this study indicate high incidence of risk factors for hearing impairment in this population of babies. Gestational age at birth had a strong, statistically significant, correlation with risk factor incidence in lower gestational age and vice versa. High incidence of risk factors and their interaction could account for twenty times higher occurrence of congenital and early acquired hearing loss in population of preterm babies compared to term neonates. These results imply the need for systematic audiological surveillance of prematurely born babies at least until 12 months of corrected age.

Nowadays nearly 10% of all births in western countries are premature. In the last decade, there has been an increase of 45% in the number of neonates that were born in Israel. At the same time, the survival of neonates, especially those with very low birth weight, VLBW, (less than 1,500 gr), has increased dramatically. Diagnostic radiology plays an important role in the assessment and treatment of neonates requiring intensive care. During their prolonged and complex hospitalization, these infants are exposed to multiple radiographic examinations involving X-ray radiation. The extent of the examinations that the infant undergoes depends on its birth weight, gestational age and its medical problems, where most of the treatment effort is focused especially on VLBW neonates. Most of the diagnostic X-ray examinations taken during the hospitalization of neonates in the neonatal intensive care unit (NICU) consist of imaging of the respiratory and gastrointestinal systems, namely, the chest and abdomen. The imaging process is done using mobile X-ray units located at the NICUs. Due to their long hospitalization periods and complex medical condition, all neonates, and neonates with VLBW in particular, are exposed to a much higher level of diagnostic radiation, compared to normal newborns. The goal of this research was to assess the extent of the exposure of neonates in Israel to X-ray radiation during their hospitalization at the neonatal intensive care unit. Five NICUs, located at different geographical zones in Israel and treating 20% of all newborns in Israel every year, participated in this research. The research was conducted in three phases: Phase I: Collection of information on radiographic techniques and exposure parameters (e.g. kV, mAs, focus to skin distance (FSD), examination borders). 499 X-ray examinations (from 157 neonates) were evaluated for necessary and unnecessary exposure of the neonate's organs to X-ray radiation during these examinations.

Full Text Available It has been proposed that neonatal thyroid-stimulating hormone (TSH concentrations are a good indicator of iodine deficiency in the population. A frequency of neonatal TSH concentrations above 5 mU/L below 3% has been proposed as the threshold indicating iodine sufficiency. The objective of the present study was to evaluate feasibility and usefulness of nation-wide neonatal TSH concentration screening results to assess iodine status in Belgium. All newborns born in Belgium during the period 2009-2011 (n = 377713 were included in the study, except those suffering from congenital hypothyroidism and premature neonates. The frequency of neonatal TSH concentrations above 5 mU/L from 2009 to 2011 in Belgium fluctuated between 2.6 and 3.3% in the centres using the same TSH assay. There was a significant inverse association between neonatal TSH level and birth weight. The longer the duration between birth and screening, the lower the TSH level. Neonatal TSH levels were significantly lower in winter than in spring or autumn and significantly lower in spring and summer than in autumn while significantly higher in spring compared to summer. In conclusion, despite that pregnant women in Belgium are mildly iodine deficient, the frequency of neonatal TSH concentrations above 5 mU/L was very low, suggesting that the neonatal TSH threshold proposed for detecting iodine deficiency needs to be re-evaluated. Although neonatal TSH is useful to detect severe iodine deficiency, it should not be recommended presently for the evaluation of iodine status in mildly iodine deficient regions.

Full Text Available Premature ejaculation (PE is a common male sexual disorder. Recent normative data suggests that men with an intravaginal ejaculatory latency time (IELT of less than 1 minute have "definite" PE, while men with IELTs between 1 and 1.5 minutes have "probable" PE. Although there is insufficient empirical evidence to identify the etiology of PE, there is limited correlational evidence to suggest that men with PE have high levels of sexual anxiety and inherited altered sensitivity of central 5-HT (5-hydroxytryptamine, serotonin receptors. Pharmacological modulation of the ejaculatory threshold using off-label daily or on-demand selective serotonin re-uptake inhibitors is well tolerated and offers patients a high likelihood of achieving improved ejaculatory control within a few days of initiating treatment, consequential improvements in sexual desire and other sexual domains. Investigational drugs such as the ejaculo-selective serotonin transport inhibitor, dapoxetine represent a major development in sexual medicine. These drugs offer patients the convenience of on-demand dosing, significant improvements in IELT, ejaculatory control and sexual satisfaction with minimal adverse effects.

Full Text Available This article considers the psychophysiological and neuroendocrine differences characteristic of premature children, which are as a result of long-term perinatal consequences. Particular emphasis is laid on the effects of the hypothalamic-pituitary-adrenocortical stress system, the performance of which is reprogramed during complicated pregnancy, labor, and postnatal period under pain stress due to medical manipulations. Being extremely sensitive to all these exposures, the brain of a premature infant develops during activation of the stress system and takes on a few distinctive properties in addition to independent neuroanatomical distinctions due to premature birth. The altered neurohormonal patterns revealed in very prematurely born children and adolescents involve the regulation of mental processes, behavior, metabolism, and circadian rhythms (sleep-wake regulation, which differ from those in their maturely born peers. These cases allow learning and behavior problems and lower cognitive estimates to be considered in normally developing children born extremely prematurely who have also hormonal dysregulation.

Objective This retrospective cohort study examined the effect of birth order on neonatal morbidity and mortality in very preterm twins. Study Design Using 2005 to 2012 data from the Canadian Neonatal Network, very preterm twins born between 24 0/7 and 32 6/7 weeks of gestation were included. Odds of morbidity and mortality of second-born cotwins compared with first-born cotwins were examined by matched-pair analysis. Outcomes were neonatal death, severe brain injury (intraventricular hemorrhage grade 3 or 4 or persistent periventricular echogenicity), bronchopulmonary dysplasia, severe retinopathy of prematurity (ROP) (> stage 2), necrotizing enterocolitis (≥ stage 2), and respiratory distress syndrome (RDS). Multivariable analysis was performed adjusting for confounders. Result There were 6,636 twins (3,318 pairs) included with a mean gestational age (GA) of 28.9 weeks. A higher rate of small for GA occurred in second-born twins (10 vs. 6%). Mortality was significantly lower for second-born twins (4.3 vs. 5.3%; adjusted odds ratio: 0.75; 95% confidence interval [CI]: 0.59-0.95). RDS (66 vs. 60%; adjusted odds ratio: 1.40; 95% CI: 1.29-1.52) and severe retinopathy (9 vs. 7%; adjusted odds ratio: 1.46; 95% CI: 1.07-2.01) were significantly higher in second-born twins. Conclusion Thus, while second-born twins had reduced odds of mortality, they also had increased odds of RDS and ROP. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.
Full Text Available Objective To observe the effect of hypertensive disorders during pregnancy (HDP on neonatal outcomes and umbilical artery flow. Methods A prospective cohort study method was employed, and 60 pregnant women met the HDP diagnostic criteria (HDP group, aged 31.2±6.0 years, gestation time 251.0±9.0d, hospitalized from Sep. 2011 to May. 2012, and delivered live-born infants and 63 pregnant women with normal blood pressure and without medical or surgical ailments (control group, aged 30.2±2.8 years, gestation time 251.9±7.7d, hospitalized in the the same period, and had live birth were involved in present study. The indexes of umbilical artery blood flow were measured, the adverse neonatal outcomes (neonatal asphyxia, low birth weight babies and premature labor were recorded, and the correlation was analyzed between the adverse neonatal outcomes and the indexes of umbilical artery blood flow. Results The incidence of adverse neonatal outcomes (neonatal asphyxia, low birth weight newborns and premature labor was higher in HDP group (58.3%, 45.0% and 53.3%, respectively than in control group (6.3%, 3.2% and 3.2%, respectively, P<0.05. The results of umbilical artery blood flow indexes, including pulsatility index (PI, resistance index (RI and systolic/diastolic ratio (S/D in HDP group (0.897±0.176, 0.588±0.701 and 2.655±0.346, respectively were significantly higher than in control group (0.741±0.123, 0.525±0.650 and 2.120±0.364, respectively, P<0.05. The indexes of umbilical artery blood flow (PI, RI and S/D in newborns with adverse outcomes were significantly higher than in those newborn without adverse outcomes. Multivariate logistic regression revealed a positive correlation between RI and adverse neonatal outcomes. Conclusions The indexes of umbilical artery blood flow appear to be abnormal in pregnant women with HDP, and adverse neonatal conditions (neonatal asphyxia, low birth weight newborns and premature labor are prone to

Full Text Available This qualitative study aims to identify and analyze the meanings the health team attributes to the parents' participation in the care of premature children hospitalized at a public hospital. Data were recorded and collected through semi-structured interviews performed with 23 professionals. The results show that parents' participation in the care of these children is still in an initial stage at the hospital's neonatal unit. However, there is interest from the health team to implement it because its importance is recognized in improving the clinical stability, the growth and development process of premature children. In addition to allowing for mother-child interaction and affective bonding, it prepares the mother for the child's discharge. The presence of the mother helps the nursing team by giving maternal care to the hospitalized child. On the other hand, the parents' presence interferes in the environment of the neonatal unit. It affects the work dynamics and creates insecurity among team workers, who feel supervised. Besides, there is concern regarding hospital infection. Thus, in accordance with other studies from different countries, these meanings entail reflections on the need to base the premature care in terms of collectively building a care philosophy that restores concepts of human rights, citizenship, bonding and mother-child attachment, pediatric psychology and also expands the concept of training for a participative health education.El estudio tiene como objetivo identificar y analizar los significados atribuidos por el equipo de salud con relación a la participación de la madre/padre en el cuidado del niño prematuro hospitalizado en un hospital público.

Full Text Available Very preterm birth is associated with an increased prevalence of attention problems and may especially impair executive attention, i.e., top-down control of attentional selection in situations where distracting information interferes with the processing of task-relevant stimuli. While there are initial findings linking structural brain alterations in preterm-born individuals with attention problems, the functional basis of these problems are not well understood. The present study used an fMRI adaptation of the Attentional Network Test to examine the neural correlates of executive attention in a large sample of N = 86 adults born very preterm and/or with very low birth weight (VP/VLBW, and N = 100 term-born controls. Executive attention was measured by comparing task behavior and brain activations associated with the processing of incongruent vs. congruent arrow flanker stimuli. Consistent with subtle impairments of executive attention, the VP/VLBW group showed lower accuracy and a tendency for increased response times during the processing of incongruent stimuli. Both groups showed similar activation patters, especially within expected fronto-cingulo-parietal areas, but no significant between-group differences. Our results argue for a maintained attention-relevant network organization in high-functioning preterm born adults in spite of subtle deficits in executive attention. Gestational age and neonatal treatment variables showed associations with task behavior, and brain activation in the dorsal ACC and lateral occipital areas, suggesting that the degree of prematurity (and related neonatal complications has subtle modulatory influences on executive attention processing.

Among infants with type 1, type 2, or no retinopathy of prematurity, the incidence of type 1 or type 2 retinopathy of prematurity in births from spontaneous preterm labor, medical indication of preterm birth, and preterm premature rupture of the membranes was 37 of 218 (17%), 27 of 272 (10%), and 10 of 164 (6%), respectively. Adjusted for gestational age, birth weight, and multiparity and compared with the preterm premature rupture of the membranes group, the odds ratios of spontaneous preterm labor and medical indication of preterm birth for type 1 or type 2 retinopathy of prematurity were 6.1 (95% confidence interval, 1.8 to 20, P = .003) and 5.5 (95% confidence interval, 1.4 to 21, P = .01), respectively. Among neonates born after preterm premature rupture of the membranes, the probability of developing type 1 or type 2 retinopathy of prematurity was greatest in infants with rupture of membrane duration of up to 24 hours. After 24 hours, the probability of developing type 1 or type 2 retinopathy of prematurity declined. The odds of developing type 1 or type 2 retinopathy of prematurity was 9.0 (95% confidence interval 2.3 to 34, P = .002) in infants who had preterm premature rupture of the membranes ≤ 24 hours compared with infants who had preterm premature rupture of the membranes > 24 hours. Type 1 or type 2 retinopathy of prematurity are adverse ocular outcomes linked with not only lower gestational age and birth weight at delivery but also with events in the intrauterine environment that trigger a preterm birth. The reduced incidence of type 1 or type 2 retinopathy of prematurity in the preterm premature rupture of the membranes group compared with other causes of preterm birth may be

A small percentage of neonates with sacrococcygeal teratoma die shortly after birth from hemorrhagic complications. The incidence of and risk factors associated with hemorrhagic mortality are unknown. In this multicenter study we determined the incidence of early death in neonates born with SCT and evaluated potential risk factors for hemorrhagic mortality. 235 children with SCT treated from 1970 to 2010 in the Netherlands were retrospectively included. The following candidate risk factors for hemorrhagic mortality were examined: sex, prematurity, Altman type, tumor volume, tumor histology, necessity of emergency operation and time of diagnosis. Eighteen patients (7.7%) died at a median age of 163.5days (range 1.7-973days). Nine patients died of a malignancy. Nine others (3.8%) died postnatally (age 1-27days), six even within two days after birth. In seven of these nine patients death was related to tumor-hemorrhage and/or circulatory failure. Risk factors for hemorrhagic mortality were prematurity, tumor volume>1000cm 3 and performance of an emergency operation. Hemorrhagic mortality of neonates with SCT is relatively high (3.8%) representing almost 70% of the overall mortality in the neonatal period. High-output cardiac failure, internal tumor hemorrhage and perioperative bleeding were the most common causes of early death and were all strongly associated with larger tumor sizes.

Neonates represent a unique and highly vulnerable patient population. Advances in medical technology that have occurred over the last few decades have improved the survival and quality of life for neonates, particularly those infants born with extreme prematurity or with congenital defects. Although immunologic immaturity and altered cutaneous barriers play some role in the vulnerability of neonates to nosocomial infections, clearly, therapeutic interventions that have proven to be lifesaving for these fragile infants also appear to be associated with the majority of infectious complications resulting in neonatal morbidity and mortality. Rates of infections in neonatal intensive care units (NICUs) have varied from 6% to 40% of neonatal patients, with the highest rates in those facilities having larger proportions of very low-birth-weight infants (birthweight NICU infants include the following: (1) optimal infection control practices, especially good hand hygiene and good nursery design; (2) prudent use of invasive interventions with particular attention to early removal of invasive devices after they are no longer essential; and (3) judicious use of antimicrobial agents, with an emphasis on targeted (narrow spectrum) rather than broad-spectrum antibiotics and appropriate indications (proven or suspected bacterial infections).

Full Text Available Objective. Current American retinopathy of prematurity (ROP screening guidelines is imprecise for infants ≥ 30 weeks with birth weights between 1500 and 2000 g. Our objective was to evaluate a risk factor based approach for screening premature infants at low risk for severe ROP. Study Design. We performed a 13-year review from Intermountain Health Care (IHC data. All neonates born at ≤32 weeks were reviewed to determine ROP screening and/or development of severe ROP. Severe ROP was defined by stage ≥ 3 or need for laser therapy. Regression analysis was used to identify significant risk factors for severe ROP. Results. We identified 4607 neonates ≤ 32 weeks gestation. Following exclusion for death, with no retinal exam or incomplete data, 2791 (61% were included in the study. Overall, severe ROP occurred in 260 (9.3%, but only 11/1601 ≥ 29 weeks (0.7%. All infants with severe ROP ≥ 29 weeks had at least 2 identified ROP risk factors. Implementation of this risk based screening strategy to the IHC population over the timeline of this study would have eliminated screening in 21% (343/1601 of the screened population. Conclusions. Limiting ROP screening for infants ≥ 29 and ≤ 32 weeks to only those with clinical risk factors could significantly reduce screening exams while identifying all infants with severe ROP.
Full Text Available In its attempt to realize the intervention program to saving newborn babies with asphyxia, the Ministry of Health will initiate to train midwives in the village in order to that they know how to operate resuscitation equipment to save neonatal baby with asphyxia. The intervention program his dubbed successful if the mortality proportion due if asphyxia decreased to half as targeted. The survey was conducted in the rural area of Cirebon district. The sample was 200 neonatal death babies, calculated using the hypothesis test with different proportion; p1 0.3 (30% neonatal death cause of asphyxia, according household health survey 2001, p2 0.15, α 0.05, β 0.2, (l-β 0.8. Neonatal dead cases happened within 12 months prior to the survey were identified by rural midwives out of their personal records. The death cases were followed up by interviewing the mother of the neonatal baby concerning its birth, illness or disorder histories before death. The diagnosis of the diseases were based on the International Classification of Diseases 10 and Wigglesworth classification, determined in union by NIHRD researchers and neonatologists. The neonatal mortality rate was 13 out of 1,000 live births. The major cause of early neonatal mortality was respiration disorder mainly caused by birth asphyxia (45%, of which 90 percent could be intervened by doing resuscitation (for babies weighed more than 1.000 gram. The second and third order of the mortality causes was infection (22% and congenital disorders (11% respectively. The major cause of late neonatal mortality was infection (56%, followed by low birth weight and prematurely born, as well as neonatal jaundice (14 percent each, and congenital disorder comes in the third place. The option to handle asphyxia with the early neonatal babies is the right effort to decrease the neonatal mortality rate. And to achieve the utmost result, it is necessary that the rural midwives maintain their standard performance (in
Full Text Available A premature male infant was born at 30 weeks’ gestation with a birth weight of 1,700 g in a rural hospital. He was diagnosed with respiratory distress syndrome and received continuous positive airway pressure treatment for 26 days. At 26 days after birth, the patient was transferred to our hospital for further evaluation and management. A comprehensive eye examination revealed a stage 3 retinopathy of prematurity (ROP involving zone 2 in both eyes. The patient was recommended to a provincial-level eye hospital for emergency laser therapy. Five months after birth, the feedback from the eye hospital showed that the patient had a high risk of blindness in both eyes. Our case report shows that delaying first screening examination increases the possibility of developing aggressive posterior ROP in infants with ROP. Doctors in rural hospitals should be aware of this possibility and trained for early screening and treatment in high-risk infants.

To address the hypothesis that pre-eclampsia (PE) impacts the fetal immune system, we investigated the prevalence of distinct immune cell subsets along with plasma cortisol and cytokine levels in pre-term newborns of PE mothers. Cord blood and peripheral blood samples on the 1st, 3rd and 7th postnatal days of life were collected from 14 pre-term infants affected by PE and 14 non-PE pregnancies. We measured plasma cortisol and cytokine levels with immunoassays and assessed the prevalence of T, NK and DC subsets using flow cytometry. The prevalence of CD4+ cells was lower in PE infants, while that of memory T cells was higher. Myeloid DCs had a lower prevalence in PE neonates. Cytokine and cortisol levels were lower in PE neonates. Our observations show that PE pregnancies are associated with altered newborn immune status during the first week of life. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Difficulties with reading and math occur more commonly among children born extremely preterm than among children born at term. Reasons for this are unclear. We measured the concentrations of 27 inflammatory-related and neurotrophic/angiogenic proteins (angio-neurotrophic proteins) in multiple blood specimens collected a week apart during the first postnatal month from 660 children born before the 28th week of gestation who at age 10 years had an IQ ≥ 70 and a Wechsler Individual Achievement Test 3rd edition (WIAT-III) assessment. We identified four groups of children, those who had a Z-score ≤ -1 on the Word Reading assessment only, on the Numerical Operations assessment only, on both of these assessments, and on neither, which served as the referent group. We then modeled the risk of each learning limitation associated with a top quartile concentration of each protein, and with high and lower concentrations of multiple proteins. The protein profile of low reading scores was confined to the third and fourth postnatal weeks when increased risks were associated with high concentrations of IL-8 and ICAM-1 in the presence of low concentrations of angio-neurotrophic proteins. The profile of low math scores was very similar, except it did not include ICAM-1. In contrast, the profile of low scores on both assessments was present in each of the first four postnatal weeks. The increased risks associated with high concentrations of TNF-α in the first two weeks and of IL-8 and ICAM-1 in the next two weeks were modulated down by high concentrations of angio-neurotrophic proteins. High concentrations of angio-neurotrophic proteins appear to reduce/moderate the risk of each learning limitation associated with systemic inflammation. The three categories of limitations have protein profiles with some similarities, and yet some differences, too. Copyright © 2018 ISDN. Published by Elsevier Ltd. All rights reserved.

Objectives: This study aimed to evaluate the changing survival rate and morbidities among infants born before 26 gestational weeks at the Sultan Qaboos University Hospital (SQUH) in Muscat, Oman. Methods: This retrospective study assessed the mortality and morbidities of all premature infants born alive at 23–26 gestational weeks at SQUH between June 2006 and May 2013. Infants referred to SQUH within 72 hours of birth during this period were also included. Electronic records were reviewed for gestational age, gender, birth weight, maternal age, mode and place of delivery, antenatal steroid administration, morbidity and outcome. The survival rate was calculated and findings were then compared with those of a previous study conducted in the same hospital from 1991 to 1998. Rates of major morbidities were also calculated. Results: A total of 81 infants between 23–26 gestational weeks were admitted to the neonatal unit during the study period. Of these, 58.0% were male and 42.0% were female. Median gestational age was 25 weeks and mean birth weight was 770 ± 150 g. Of the 81 infants, 49 survived. The overall survival rate was 60.5% compared to 41% reported in the previous study. Respiratory distress syndrome (100.0%), retinopathy of prematurity (51.9%), bronchopulmonary dysplasia (34.6%), intraventricular haemorrhage (30.9%) and patent ductus arteriosus (28.4%) were the most common morbidities. Conclusion: The overall survival rate of infants between 23–26 gestational weeks during the study period had significantly improved in comparison to that found at the same hospital from 1991 to 1998. There is a need for the long-term neurodevelopmental follow-up of premature infants. PMID:26357555

To assess the natural history and contemporary outcomes in pregnancies complicated by previable preterm premature rupture of membranes (PROM). Retrospective study of all women with a singleton or twin pregnancy admitted to a single tertiary referral center who experienced preterm PROM between 20 and 23 6/7 weeks of gestation during 2004-2014 and underwent expectant management. Women electing termination of pregnancy and pregnancies complicated by major fetal anomalies were excluded. Severe neonatal morbidity was defined as a composite of bronchopulmonary dysplasia, severe neurologic injury, or severe retinopathy of prematurity. Long-term follow-up to a corrected age of 18-21 months was available for the majority of surviving neonates. Of the 140 neonates born to women with previable preterm PROM during the study period, 104 were eligible for the study. Overall 51 (49.0%, 95% confidence interval [CI] 39.4-58.6%) newborns survived to discharge, of whom 24 (47.1%, 95% CI 33.4-60.8%) experienced severe neonatal morbidity. The overall rate of long-term morbidity among surviving neonates was 23.3% (95% CI 11.7-34.9%) and was significantly higher among neonates who previously experienced severe neonatal morbidity compared with those who did not (39.1% compared with 10.0%, P=.04). The only two factors that were significantly associated with overall survival and survival without severe neonatal morbidity were gestational age at preterm PROM of 22 weeks or greater (adjusted odds ratio [OR] 12.2, 95% CI 3.3-44.8 and adjusted OR 4.8, 95% CI 1.2-19.3, respectively) and a latency period of greater than 7 days (adjusted OR 10.1, 95% CI 3.2-31.6, and adjusted OR 6.7, 95% CI 2.2-21.0, respectively). Expectant management was associated with maternal risks including placental abruption (17.3%, 95% CI 10.0-24.6%) and sepsis (4.8%, 95% CI 0.7-8.9%). Expectant management in pregnancies complicated by previable preterm PROM between 20 and 23 6/7 weeks of gestation is associated with an

Retinopathy of prematurity is a retinal vasoproliferative disease affecting extremely preterm infants exposed to high concentrations of oxygen therapy. Infants born before 32 post-menstrual weeks or with a birth weight of less than 1500g should systematically have a dilated fundus examination. The time of screening and schedule for follow-up are guided by the various risk factors. This disease results from immaturity of the peripheral retinal vessels at the time of premature birth. The classification of ROP depends on the anteroposterior extent of involvement (from center to periphery: zone I, II and III), its extension in 30° sectors (clock hours) and its stage (stage 1 to 5). "Plus" disease is defined as dilation and tortuosity of the retinal blood vessels in the posterior pole of the eye and represents a major risk factor for rapid unfavorable progression. A majority of patients will spontaneously recover, but patients with a high risk of progression will require treatment to prevent retinal detachment and blindness. The indications for treatment are threshold disease and type 1 pre-threshold disease. The current treatment of choice is peripheral retinal ablation with transpupillary laser, but ab externo cryotherapy may be used instead. Intravitreal injection of vascular endothelial growth factor inhibitors may be an attractive therapeutic option and is currently under investigation. After laser treatment, unfavorable outcomes occur in only 9 to 14 % of eyes, but at the price of peripheral retinal destruction. For all patients, whether treated or not, a regular fundus examination should be insured until complete retinal vascularization has occurred. Copyright © 2017 Elsevier Masson SAS.

Term infants with hypertrophic pyloric stenosis (HPS) typically present between 4 and 6 weeks. There is limited consensus, however, regarding age of presentation of premature infants. We aim to determine if there is an association between the degree of prematurity and chronological age of presentation of HPS. A total of 2988 infants who had undergone a pyloromyotomy for HPS were identified from the 2012 and 2013 NSQIP-P Participant Use Files. Two hundred seventeen infants (7.3%) were born prematurely. A greater degree of prematurity was associated with an older chronological age of presentation ( P Prematurity was significantly associated with an increase in overall postoperative morbidity, reintubation, readmission, and postoperative length of stay. When clinicians evaluate an infant with nonbilious emesis with a history of prematurity, they should consider pyloric stenosis if the calculated postconceptional age is between 44 and 50 weeks. When counseling families of premature infants, surgeons should discuss the increased incidence of postpyloromyotomy morbidity.

Neonatal near miss cases occur more often than neonatal deaths and could enable a more comprehensive analysis of risk factors, short-term outcomes and prognostic factors in neonates born to mothers with severe obstetric complications. The objective was to assess the incidence, presentation and perinatal outcomes of severe obstetric morbidity in two referral hospitals in Central Uganda. A prospective cohort study was conducted between March 1, 2013 and February 28, 2014, in which all newborns from cases of severe pregnancy and childbirth complications were eligible for inclusion. The obstetric conditions included obstetric haemorrhage, hypertensive disorders, obstructed labour, chorioamnionitis and pregnancy-specific complications such as malaria, anemia and premature rupture of membranes. Still births, neonatal deaths and neonatal near miss cases (defined using criteria that employed clinical features, presence of organ-system dysfunction and management provided to the newborns were compiled). Stratified and multivariate logistic regression analysis was conducted to identify risk factors for perinatal death. Of the 3100 mothers, 192 (6.2%) had abortion complications. Of the remainder, there were 2142 (73.1%) deliveries, from whom the fetal outcomes were 257 (12.0%) still births, 369 (17.2%) neonatal deaths, 786 (36.7%) neonatal near misses and 730 (34.1%) were newborns with no or minimal life threatening complications. Of the 235 babies admitted to the neonatal intensive care unit (NICU), the main reasons for admission were prematurity for 64 (26.8%), birth asphyxia for 59 (23.7%), and grunting respiration for 26 (11.1%). Of the 235 babies, 38 (16.2%) died in the neonatal period, and of these, 16 died in the first 24 hours after admission. Ruptured uterus caused the highest case-specific mortality of 76.8%, and led to 16.9% of all newborn deaths. Across the four groups, there were significant differences in mean birth weight, p = 0.003. Antepartum hemorrhage

Although the survival rate for preterm subjects has improved considerably, due to the progress in the field of perinatal medicine, preterm birth is frequently the cause underlying a series of notorious complications: morphological, neurological, ophthalmological, and renal alterations. In addition, it has recently been demonstrated how low gestational age and reduced foetal growth contribute towards an increased cardiovascular risk in preterm neonates. In fact, cardiovascular mortality is higher among former preterm adults than those born at term. This condition is referred to as cardiovascular perinatal programming. In the light of the above, an early, constant, and prolonged cardiological followup programme should be implemented in former preterm individuals. The aim of this paper was to perform a comprehensive literature review about two new emerging conditions predisposing to an increased cardiovascular risk: prematurity and low weight at birth.

To compare amplitude-integrated EEG (aEEG) and conventional EEG (EEG) activity in premature neonates. Biweekly aEEG and EEG were simultaneously recorded in a cohort of infants born less than 34 weeks gestation. aEEG recordings were visually assessed for lower and upper border amplitude and bandwidth. EEG recordings were compressed for visual evaluation of continuity and assessed using a signal processing software for interburst intervals (IBI) and frequencies' amplitude. Ten-minute segments of aEEG and EEG indices were compared using regression analysis. A total of 189 recordings from 67 infants were made, from which 1697 aEEG/EEG pairs of 10-minute segments were assessed. Good concordance was found for visual assessment of continuity between the 2 methods. EEG IBI, alpha and theta frequencies' amplitudes were negatively correlated to the aEEG lower border while conceptional age (CA) was positively correlated to aEEG lower border ( P continuity and amplitude.

Tertiary Centres of Excellence in India have been at the forefront of the efforts against Retinopathy of Prematurity (ROP) - associated blindness. The epidemic of blindness from ROP; however, has now spread rapidly into large parts of interiors of developing countries due to improved newborn care facilities. Due to their knowledge and experience of more than a decade, these centres of excellence, both from child care and Ophthalmology care, now need to come forward in substantial measures and need to be supported by funds and programs so that concerns of neonatal eye-health, training, screening, prevention and treatment can get integrated and embedded into newborn critical care and health programs. This will protect newborn preterm survivors from losing the potentially good vision that they are born with, reduce the rapidly rising blindness epidemic, and also protect staff from potential high-value litigations.

-1,500 g and 23-33 weeks of gestational age (GA, without malformations, who were born alive at eight public university tertiary hospitals in Brazil between June of 2004 and May of 2005. Infants who died within their first 6 days of life were compared with those who did not regarding maternal and neonatal characteristics and morbidity during the first 72 hours of life. Variables associated with the early deaths were identified by stepwise logistic regression. RESULTS: A total of 579 live births met the inclusion criteria. Early deaths occurred in 92 (16% cases, varying between centers from 5 to 31%, and these differences persisted after controlling for newborn illness severity and mortality risk score (SNAPPE-II. According to the multivariate analysis, the following factors were associated with early intrahospital neonatal deaths: gestational age of 23-27 weeks (odds ratio - OR = 5.0; 95%CI 2.7-9.4, absence of maternal hypertension (OR = 1.9; 95%CI 1.0-3.7, 5th minute Apgar 0-6 (OR = 2.8; 95%CI 1.4-5.4, presence of respiratory distress syndrome (OR = 3.1; 95%CI 1.4-6.6, and network center of birth. CONCLUSION: Important perinatal factors that are associated with early neonatal deaths in very low birth weight preterm infants can be modified by interventions such as improving fetal vitality at birth and reducing the incidence and severity of respiratory distress syndrome. The heterogeneity of early neonatal rates across the different centers studied indicates that best clinical practices should be identified and disseminated throughout the country.

Widespread brain changes are present in preterm born infants, adolescents, and even adults. While neurobiological models of prematurity facilitate powerful explanations for the adverse effects of preterm birth on the developing brain at microscale, convincing linking principles at large-scale level to explain the widespread nature of brain changes are still missing. We investigated effects of preterm birth on the brain's large-scale intrinsic networks and their relation to brain structure in preterm born adults. In 95 preterm and 83 full-term born adults, structural and functional magnetic resonance imaging at-rest was used to analyze both voxel-based morphometry and spatial patterns of functional connectivity in ongoing blood oxygenation level-dependent activity. Differences in intrinsic functional connectivity (iFC) were found in cortical and subcortical networks. Structural differences were located in subcortical, temporal, and cingulate areas. Critically, for preterm born adults, iFC-network differences were overlapping and correlating with aberrant regional gray-matter (GM) volume specifically in subcortical and temporal areas. Overlapping changes were predicted by prematurity and in particular by neonatal medical complications. These results provide evidence that preterm birth has long-lasting effects on functional connectivity of intrinsic networks, and these changes are specifically related to structural alterations in ventral brain GM. © The Author 2014.

We aimed to indirectly assess the contribution from observer bias to between centre variability in the incidence of acute retinopathy of prematurity (ROP). The Australian and New Zealand Neonatal Network (ANZNN) collected data on the highest stage of acute ROP in either eye in 2286 infants born at less than 29 weeks in 1998-1999 and cared for in one of 25 neonatal intensive care units (NICUs). Chi-squared analysis was used to detect differences in the proportion of stages of ROP for each neonatal intensive care unit. These proportions were compared with those reported in two large studies of treatment for ROP. The incidence of acute ROP in the ANZNN cohort was 42% and the ratio of stage 1:2:3 ROP was 1.5:1.9:1. There was considerable variation in both the incidence of acute ROP and the proportions with stage 1:2:3 ROP between centres. A chi-squared test determined that the assignment of stages 1, 2 and 3/4 ROP was not independent of centre (chi(2)(48) = 165.2; P < 0.0001). Treatment of stage 3 ROP varied between 15% and 120%, indicating some eyes were treated at less than stage 3. The data are highly suggestive of observer bias contributing to the observed between centre variation in the incidence of acute ROP. In neonatal intervention studies where acute ROP is an outcome it would seem important to have an accreditation process for examining ophthalmologists, and there are similar arguments for neonatal networks which collect these data.

Systemic lupus erythematosus (SLE) and antiphospholipid antibody syndrome (APS) are autoimmune diseases that affect women of childbearing age. Pregnancies in these patients carry several complications such as prematurity. Maternal IgG antiphospholipid antibodies (aPL) can cross the placenta but they don't generally cause any neonatal thrombotic event. Because of the incompleteness of the fetal blood-brain barrier, aPL could theoretically reach the fetal brain. Whether this can have an effect on brain development is still under investigation. Some studies performed in children of patients with SLE and/or APS showed an increased number of learning disabilities without impairment in intelligence level. The objectives of this article are to evaluate the neurodevelopment outcome in 30 children (median age 9 years) born to mothers with SLE and/or APS with IgG anti-beta2-glycoprotein I during the third trimester of pregnancy and found positive for the same antibodies at birth. A neurological physical exam was performed in all children. We submitted some questionnaires to the mothers: the Child Behavior CheckList (CBCL) and a homemade set of questions obtained by a team composed of rheumatologists and pediatric neurologists. Intellectual functioning was determined by the Wechsler scale for corrected age. In all children neurological physical exam and intelligence levels were found to be normal but mild behavior disorders and history of neurological manifestations were shown in three children. Offspring of patients with SLE and/or APS are generally healthy. We and others observed the occurrence of minor neurological disorders that might be related to maternal disease or to prematurity. The limited number of the available data on this sensitive issue supports the need for further studies. © The Author(s) 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

To compare different neonatal outcomes according to the different types of treatments used in the management of gestational diabetes mellitus. This was a retrospective cohort study. The study population comprised pregnant women with gestational diabetes treated at a public maternity hospital from July 2010 to August 2014. The study included women aged at least 18 years, with a singleton pregnancy, who met the criteria for gestational diabetes mellitus. Blood glucose levels, fetal abdominal circumference, body mass index and gestational age were considered for treatment decision-making. The evaluated neonatal outcomes were: type of delivery, prematurity, weight in relation to gestational age, Apgar at 1 and 5min, and need for intensive care unit admission. The sample consisted of 705 pregnant women. The neonatal outcomes were analyzed based on the treatment received. Women treated with metformin were less likely to have children who were small for gestational age (95% CI: 0.09-0.66) and more likely to have a newborn adequate for gestational age (95% CI: 1.12-3.94). Those women treated with insulin had a lower chance of having a preterm child (95% CI: 0.02-0.78). The combined treatment with insulin and metformin resulted in higher chance for a neonate to be born large for gestational age (95% CI: 1.14-11.15) and lower chance to be born preterm (95% CI: 0.01-0.71). The type of treatment did not affect the mode of delivery, Apgar score, and intensive care unit admission. The pediatrician in the delivery room can expect different outcomes for diabetic mothers based on the treatment received. Copyright © 2016 Sociedade Brasileira de Pediatria.

Results: The sample consisted of 705 pregnant women. The neonatal outcomes were analyzed based on the treatment received. Women treated with metformin were less likely to have children who were small for gestational age (95% CI: 0.09-0.66 and more likely to have a newborn adequate for gestational age (95% CI: 1.12-3.94. Those women treated with insulin had a lower chance of having a preterm child (95% CI: 0.02-0.78. The combined treatment with insulin and metformin resulted in higher chance for a neonate to be born large for gestational age (95% CI: 1.14-11.15 and lower chance to be born preterm (95% CI: 0.01-0.71. The type of treatment did not affect the mode of delivery, Apgar score, and intensive care unit admission. Conclusions: The pediatrician in the delivery room can expect different outcomes for diabetic mothers based on the treatment received.
Full Text Available Cronobacter is a class of Enterobacteriaceae that cause infections in neonates, especially those born prematurely. Over 90% of these infections have been linked epidemiologically to powdered infant formula (PIF. Contamination of PIF can occur at manufacture, reconstitution, or storage of reconstituted product. Intrinsic properties that enable Cronobacter to cause disease include resistance to heat, ultraviolet radiation, oxygen radicals, stomach acids, and pasteurization; an ability to utilize sialic acid (a nutrition additive to PIF that facilitates the organism’s growth and survival; and an exceptional affinity for biofilms in enteral feeding tubes. As part of ongoing endeavors to reduce the incidence of neonatal PIF-associated Cronobacter infections, the World Health Organization (WHO and the U.S. Food and Drug Administration (FDA have established guidelines for PIF production, preparation for infant feeding, and storage of reconstituted product.

The eyes of premature infants are especially vulnerable to injury after birth. A serious complication is called retinopathy of prematurity (ROP), which is abnormal growth of the blood vessels in an infant's eye. Retinopathy of prematurity develops when abnormal blood vessels grow and spread throughout the retina, which is the nerve tissue at the…
Full Text Available Graham E Quinn Division of Ophthalmology, The Children’s Hospital of Philadelphia, Wood Center, Philadelphia, PA, USA Abstract: Blindness due to retinopathy of prematurity (ROP is an increasing problem worldwide as improved levels of neonatal care are provided in countries with developing neonatal intensive care units. The occurrence of ROP blindness varies dramatically with the socioeconomic development of a country. In regions with high levels of neonatal care and adequate resources, ROP blindness is largely restricted to premature infants with very low birth weight and low gestational age while in middle- and low-income countries with regional variation in technology and capacity, limited health resources may well limit the care of the premature newborn.

It was the aim of this study to assess whether very-low-birth-weight (VLBW) infants born small for gestational age (SGA; birth weight less than 10th percentile) are at increased risk for late-onset sepsis. This was a prospective, multicenter study of the German Neonatal Network including VLBW infants from 23 to risk with coagulase-negative staphylococci in our SGA cohort. In a multivariate logistic regression analysis, higher gestational age [per week; odds ratio (OR): 0.75, 95% confidence interval (CI): 0.72-0.78, PGerman descendance (OR: 0.76, 95% CI: 0.63-0.91, P = 0.003) and prophylaxis with glycopeptide antibiotics (OR: 0.64, 95% CI: 0.47-0.87, P = 0.005) were shown to be protective against late-onset sepsis. In contrast, longer duration of parenteral nutrition (per day; OR: 1.016, 95% CI: 1.011-1.021, P risk factors (OR: 1.31, 95% CI: 1.02-1.68, P= 0.03). SGA contributes to the risk of late-onset sepsis in VLBW infants. Future studies are needed to investigate the underlying pathophysiology to guide individualized preventive measures in this vulnerable subgroup.

Background Candida is the third most common cause of late-onset neonatal sepsis in infants born at Candida infections. C. parapsilosis rates were similar in studies performed before the year 2000, 33.53 % [95% CI, 30.06, 37.40] (28 studies), to those after 2000, 27.00% [95% CI, 8.25, 88.37] (8 studies). The mortality due to neonatal Candida parapsilosis infections was 10.02% [95% CI, 7.66, 13.12]. Geographical variations in C. parapsilosis infections included a low incidence in Europe and higher incidence in North America and Australia. Biofilm formation was a significant virulence determinant and predominant risk factors for C. parapsilosis infections were prematurity, prior colonization and catheterization. Amphotericin B remains the antifungal drug of choice and combination therapy with caspofungin or other echinocandins may be considered in resistant cases. Conclusion C. parapsilosis is a significant neonatal pathogen, comprises a third of all Candida infections and is associated with 10% mortality. Availability of tools for genetic manipulation of this organism will identify virulence determinants and organism characteristics that may explain predilection for preterm neonates. Strategies to prevent horizontal transmission in the neonatal unit are paramount in decreasing infection rates. PMID:23340551
Full Text Available Abstract Background Studies comparing perinatal outcomes in multiples conceived following the use of artificial reproductive technologies (ART vs. spontaneous conception (SC have reported conflicting results in terms of mortality and morbidity. Therefore, the objective of our study was to compare composite outcome of mortality and severe neonatal morbidities amongst preterm multiple births ≤ 32 weeks gestation infant born following ART vs. SC. Methods We conducted a single center cohort study at Mount Sinai Hospital, Toronto, Ontario, Canada. Data on all preterm multiple births (≤ 32 weeks GA discharged between July 2005 and June 2008 were retrospectively collected from a prospective database at our centre. Details regarding mode of conception were collected retrospectively from maternal health records. Preterm multiple births were categorized into those born following ART vs. SC. Composite outcome was defined as combination of death or any of the three neonatal morbidities (grade 3/4 intraventricular hemorrhage or periventricular leukomalacia; retinopathy of prematurity > stage 2 or chronic lung disease. Univariate and multivariate regression analysis were preformed after adjustment of confounders (maternal age, parity, triplets, gestational age, sex, and small for gestational age. Results One hundred and thirty seven neonates were born following use of ART and 233 following SC. The unadjusted composite outcome rate was significantly higher in preterm multiples born following ART vs. SC [43.1% vs. 26.6%, p = 0.001; OR 1.98 (95% CI 1.13, 3.45]; however, when adjusted for confounders the difference between groups was not statistically significant [OR 1.39, 95% CI 0.67, 2.89]. Conclusion In our population of preterm multiple births, the mode of conception had no detectable effect on the adjusted composite neonatal outcome of mortality and/or three neonatal morbidities.

Objective: To describe characteristics and outcomes of Jordanian newborns admitted to a large governmental neonatal intensive care unit (NICU). Methods: Newborns born at the government hospital, Al Bashir, in Amman, Jordan were prospectively enrolled. The study focused on newborns admitted to the NICU and a retrospective chart review was performed. Abstraction included in-hospital mortality, antibiotic days, ventilation, oxygen use, and CRP levels. Rank sum and chi-squared tests were used to compare across outcomes. Logistic regression of hypothesized risk factors with death adjusted for gestational age. Results: Of the 5,466 neonates enrolled from 2/10-2/11, medical records were available for 321/378(84.9%) infants admitted to the NICU. The median gestational age was 36 weeks, median birth weight was 2.3 kg, and 28(8.7%) infants died. The two most common reasons for admission and mortality were respiratory distress syndrome and prematurity. Low Apgar scores and positive CRP were predictors of mortality. Risk factors associated with increased use of antibiotics, oxygen hood, and mechanical ventilation included lower gestational age and prematurity. Conclusion: Infants admitted to the Jordanian NICU have significantly higher median gestational age and birth weights than in developed countries and were associated with significant morbidity and mortality. Continuations of global efforts to prevent prematurity are needed. PMID:25946927

Full Text Available Effects of early life psychosocial adversity have received a great deal of attention, such as maternal separation in experimental animal models and abuse/neglect in young humans. More recently, long-term effects of the physical stress of repetitive procedural pain have begun to be addressed in infants hospitalized in neonatal intensive care. Preterm infants are more sensitive to pain and stress, which cannot be distinguished in neonates. The focus of this review is clinical studies of long-term effects of repeated procedural pain-related stress in the neonatal intensive care unit (NICU in relation to brain development, neurodevelopment, programming of stress systems, and later pain sensitivity in infants born very preterm (24–32 weeks’ gestational age. Neonatal pain exposure has been quantified as the number of invasive and/or skin-breaking procedures during hospitalization in the NICU. Emerging studies provide convincing clinical evidence for an adverse impact of neonatal pain/stress in infants at a time of physiological immaturity, rapidly developing brain microstructure and networks, as well as programming of the hypothalamic-pituitary-adrenal axis. Currently it appears that early pain/stress may influence the developing brain and thereby neurodevelopment and stress-sensitive behaviors, particularly in the most immature neonates. However, there is no evidence for greater prevalence of pain syndromes compared to children and adults born healthy at full term. In addressing associations between pain/stress and outcomes, careful consideration of confounding clinical factors related to prematurity is essential. The need for pain management for humanitarian care is widely advocated. Non-pharmacological interventions to help parents reduce their infant’s stress may be brain-protective.

In this thesis we investigated clinical effects of allogeneic red blood cell (RBC) transfusions in premature infants, different transfusion volumes in relation to neonatal outcome in premature infants and the use of autologous cord blood (CB) as an alternative for allogeneic transfusions. Despite the use of a national transfusion guideline, we observed significant differences concerning the total amount of administered transfusions. A liberal transfusion strategy and a higher transfusion volu...

To test the applicability of existing retinopathy of prematurity (ROP) guidelines on Iranian patients and to develop novel ROP screening criteria in Iran. Both eyes of 1932 infants born ≤37 weeks of gestation and/or weighting ≤3000 g were included in this prospective cohort study that was conducted across nine neonatal intensive care units and a tertiary eye hospital ROP clinic. The patients were examined for ROP and the need for treatment (type 1 ROP or worse). All the patients were screened 4 weeks after birth or at 31 weeks of postmenstrual age, whichever was later. The patients were followed until retinal vascularisation was completed or the patients reached 50 weeks of gestational age (GA) without prethreshold ROP. A receiver operating characteristic curve was used to determine the best screening criteria for ROP. Screening criteria from other countries were applied to our patient data to determine their ability to appropriately detect ROP. Patients with ROP requiring treatment. The mean GA±SD and birth weight (BW)±SD of the screened patients were 32±2.7 weeks and 1713±516 g, respectively. Using criteria of GA≤32 weeks or BW ≤2000 yielded sensitivity and specificity of 100% and 26.7%, respectively, for treatment requiring ROP regardless of clinical comorbidities. Using screening recommendations of American Academy of Pediatrics would miss 25.4% of ROP and 8.4%ROP requiring treatment in our cohort. Other countries screening recommendations would result in a significant amount of missed cases of treatment requiring ROP when applied to Iran. As a result, we have proposed new guidelines for premature babies in Iran. Published by the BMJ Publishing Group Limited.

As part of a supplement entitled "Born Too Soon", this paper focuses on care of the preterm newborn. An estimated 15 million babies are born preterm, and the survival gap between those born in high and low income countries is widening, with one million deaths a year due to direct complications of preterm birth, and around one million more where preterm birth is a risk factor, especially amongst those who are also growth restricted. Most premature babies (>80%) are between 32 and 37 weeks of gestation, and many die needlessly for lack of simple care. We outline a series of packages of care that build on essential care for every newborn comprising support for immediate and exclusive breastfeeding, thermal care, and hygienic cord and skin care. For babies who do not breathe at birth, rapid neonatal resuscitation is crucial. Extra care for small babies, including Kangaroo Mother Care, and feeding support, can halve mortality in babies weighing Neonatal intensive care units in high income settings are de-intensifying care, for example increasing use of continuous positive airway pressure (CPAP) and this makes comprehensive preterm care more transferable. For health systems in low and middle income settings with increasing facility births, district hospitals are the key frontier for improving obstetric and neonatal care, and some large scale programmes now include specific newborn care strategies. However there are still around 50 million births outside facilities, hence home visits for mothers and newborns, as well as women's groups are crucial for reaching these families, often the poorest. A fundamental challenge is improving programmatic tracking data for coverage and quality, and measuring disability-free survival. The power of parent's voices has been important in high-income countries in bringing attention to preterm newborns, but is still missing from the most affected countries.

The complex early history of infant incubators provides insight into challenges faced by medical professionals as they promoted care for premature infants in the early 20th century. Despite their absence from the narrative to date, nurses played vital roles in the development of neonatal care. Working in many different settings, from incubator-baby shows to the first hospital unit designed specifically for premature infants, nurses administered quality care and promoted advanced treatment for these newborns.

Children born preterm are at risk for a wide range of neurocognitive and neurobehavioral disorders. Some of these may stem from early brain abnormalities at the neonatal age. Hence, a precise characterization of neonatal neuroanatomy may help inform treatment strategies. In particular, the ventricles are often enlarged in neurocognitive disorders, due to atrophy of surrounding tissues. Here we present a new pipeline for the detection of morphological and relative pose differences in the ventricles of premature neonates compared to controls. To this end, we use a new hyperbolic Ricci flow based mapping of the ventricular surfaces of each subjects to the Poincaré disk. Resulting surfaces are then registered to a template, and a between group comparison is performed using multivariate tensor-based morphometry. We also statistically compare the relative pose of the ventricles within the brain between the two groups, by performing a Procrustes alignment between each subject's ventricles and an average shape. For both types of analyses, differences were found in the left ventricles between the two groups.

Puerto Rican children share a disproportionate burden of prematurity and asthma in the United States. Little is known about prematurity and childhood asthma in Puerto Rican subjects. We sought to examine whether prematurity is associated with asthma in Puerto Rican children. We performed a case-control study of 678 children aged 6 to 14 years with (n = 351) and without (n = 327) asthma living in San Juan, Puerto Rico. Prematurity was defined by parental report for our primary analysis. In a secondary analysis, we only included children whose parents reported prematurity that required admission to the neonatal intensive care unit. Asthma was defined as physician-diagnosed asthma and wheeze in the prior year. We used logistic regression for analysis. All multivariate models were adjusted for age, sex, household income, atopy (≥1 positive IgE level to common allergens), maternal history of asthma, and early-life exposure to environmental tobacco smoke. In a multivariate analysis there was a significant interaction between prematurity and atopy on asthma (P = .006). In an analysis stratified by atopy, prematurity was associated with a nearly 5-fold increased odds of asthma in atopic children (adjusted odds ratio, 4.7; 95% CI, 1.5-14.3; P = .007). In contrast, there was no significant association between prematurity and asthma in nonatopic children. Similar results were obtained in our analysis of prematurity requiring admission to the neonatal intensive care unit and asthma. Our results suggest that atopy modifies the estimated effect of prematurity on asthma in Puerto Rican children. Prematurity might explain, in part, the high prevalence of atopic asthma in this ethnic group. Copyright © 2013 American Academy of Allergy, Asthma & Immunology. Published by Mosby, Inc.

The treatment of a premature rupture of the foetal membrane (prom) has up to now been a subject of controversy. Depending on the stage of gestation, the prompt birth ensuing as a result of prom, involves the risk of immaturity of the child. Conservative waiting by contrast, exposes mother and child to a potential risk of infection. The retrospective study presented, summarises the strategies for treating prom used at the Cologne University Department of Obstetrics and Gynaecology during the period from 1984 to 1989, and attempts to develop from these data proposals for the treatment of prom. With an increase in latency of over 24 hours between prom and delivery, the maternal and neonatal rate of infection also increased significantly. An effective result of a prophylaxis with antibiotics could only be shown in the reduction of incidence of infection in the mother. An effect on the neonatal rate of infection could not be seen. Inducing prepartually lung-maturity with glucocorticoides or ambroxol resulted in a significant decrease of the RDS-rate in new born children up to the 34th week of gestation. Beyond the 34th week of gestation, this effect could not be found. Whereas after completion of the 37th week of gestation, the preferred treatment used by doctors is allowing the shortest possible time of latency between prom and delivery, the expected pulmonary immaturity before the 34th week of gestation has to be treated by prolonging the pregnancy and inducing pulmonary maturity under antibiotic prophylaxis and at the same time controlling infection.(ABSTRACT TRUNCATED AT 250 WORDS)

The objective was to investigate the use of autologous red blood cells (RBCs) derived from umbilical cord blood (UCB), as an alternative for allogeneic transfusions in premature infants admitted to a tertiary neonatal center. UCB collection was performed at deliveries of less than 32 weeks of gestation and processed into autologous RBC products. Premature infants requiring a RBC transfusion were randomly assigned to an autologous or allogeneic product. The primary endpoint was an at least 50 percent reduction in allogeneic transfusion needs. Fifty-seven percent of the collections harvested enough volume (> or =15 mL) for processing. After being processed, autologous products (> or =10 mL/kg) were available for 36 percent of the total study population and for 27 percent of the transfused infants and could cover 58 percent (range, 25%-100%) of the transfusion needs within the 21-day product shelf life. Availability of autologous products depended most on the gestational age. Infants born between 24 and 28 weeks had the lowest availability (17%). All products, however, would be useful in view of their high (87%) transfusion needs. Availability was highest (48%) for the infants born between 28 and 30 weeks. For 42 percent of the infants with transfusion needs in this group, autologous products were available. For the infants born between 30 and 32 weeks, autologous products were available for 36 percent of the infants. Transfusion needs in this group were, however, much lower (19%) compared to the other gestational groups. Autologous RBCs derived from UCB could not replace 50 percent of allogeneic transfusions due to the low UCB volumes collected and subsequent low product availability.
Preterm birth complication is the leading cause of neonatal death resulting in over one million deaths each year of the 15 million babies born preterm. To accelerate change, we provide an overview of the comprehensive strategy required, the tools available for context-specific health system implementation now, and the priorities for research and innovation. There is an urgent need for action on a dual track: (1) through strategic research to advance the prevention of preterm birth and (2) improved implementation and innovation for care of the premature neonate. We highlight evidence-based interventions along the continuum of care, noting gaps in coverage, quality, equity and implications for integration and scale up. Improved metrics are critical for both burden and tracking programmatic change. Linked to the United Nation's Every Women Every Child strategy, a target was set for 50% reduction in preterm deaths by 2025. Three analyses informed this target: historical change in high income countries, recent progress in best performing countries, and modelling of mortality reduction with high coverage of existing interventions. If universal coverage of selected interventions were to be achieved, then 84% or more than 921,000 preterm neonatal deaths could be prevented annually, with antenatal corticosteroids and Kangaroo Mother Care having the highest impact. Everyone has a role to play in reaching this target including government leaders, professionals, private sector, and of course families who are affected the most and whose voices have been critical for change in many of the countries with the most progress.

After approbation, was developed a phenomenological interview with nine women-mothers. The comprehensive analysis constituted eight units of significance, the hermeneutics allowed to reveal the existential movement of being-mother in the daily routine, in the ways of being of the inauthenticity and impersonality, moved by the talk, the ambiguity and fear, modes of occupation. By understanding how yours the possibility to have a premature baby, touch it gingerly and carefully, transits to an understanding in which no longer engages yourself, concerns yourself. By concerning yourself, the being-mother establishes the possibility of being-there-with-the-baby. Was possible to understand this way of being mother, in which pass by stages before seeing the baby like yours and to trust in yourself. Enable to touch the baby, understanding it in its individuality, uniqueness proved to be a care to the premature newborn in their complexity as being-there.

de la salud.The repeated painful experiences in newborns may have short- and long-time effects, especially in premature infants. The use of sweetened solutions during painful procedures has been recommended as a measure of pain relief. This study aims to evaluate the evidence of the effect of oral sucrose or glucose for acute pain relief in premature infants. An integrative review was conducted in the MEDLINE and LILACS databases. Eight articles were selected from 2005 to 2010. The analyzis of these articles revealed the analgesic effect of glucose and sucrose in acute procedures. No significant side effects were found in infants who received glucose/sucrose. We emphasize the importance of the use of the pain assessment scale most closely related to the predominant population in the Neonatal Intensive Care Unit, a scale easy to be used and handled by health professionals.

To evaluate the possible protective effect of breast milk against retinopathy of prematurity by comparing the amount of breast milk received by patients who developed retinopathy of prematurity and those who did not and to determine both the required minimum amount of breast milk and the time of life during which neonates need to receive breast milk for this effect to be significant. Cohort study of newborns with a birth weight of prematurity of any degree was 31% (100 of 323 patients) and that of severe retinopathy of prematurity was of 9% (29 of 323 patients). The median amounts of breast milk received daily by patients with and without retinopathy of prematurity were 4.9 mL/kg (interquartile range, 0.3-15.4) and 10.2 mL/kg (1.5-25.5), respectively. The amount of breast milk received in the first 6 weeks of life was inversely associated with the incidence of both retinopathy of prematurity of any degree and severe retinopathy of prematurity in the univariate analyses. However, the statistical significance was maintained only during the sixth week of life in a per-period multivariate analysis controlling for confounding factors. Small amounts of breast milk are inadequate to prevent retinopathy of prematurity in premature newborns at risk for the disease.

To determine whether severe retinopathy of prematurity (ROP) is associated with (1) abnormal white matter maturation and (2) neurodevelopmental outcomes at 18 months' corrected age (CA) compared with neonates without severe ROP. We conducted a prospective longitudinal cohort of extremely preterm neonates born 24-28 weeks' gestational age recruited between 2006 and 2013 with brain MRIs obtained both early in life and at term-equivalent age. Severe ROP was defined as ROP treated with retinal laser photocoagulation. Using diffusion tensor imaging and tract-based spatial statistics (TBSS), white matter maturation was assessed by mean fractional anisotropy (FA) in seven predefined regions of interest. Neurodevelopmental outcomes were assessed with Bayley Scales of Infant and Toddler Development-III (Bayley-III) composite scores at 18 months' CA. Subjects were compared using Fisher's exact, Kruskal-Wallis and generalised estimating equations. Families were recruited from the neonatal intensive care unit at BC Women's Hospital. Of 98 extremely preterm neonates (median: 26.0 weeks) assessed locally for ROP, 19 (19%) had severe ROP and 83 (85%) were assessed at 18 months' CA. Severe ROP was associated with lower FA in the posterior white matter, and with decreased measures of brain maturation in the optic radiations, posterior limb of the internal capsule (PLIC) and external capsule on TBSS. Bayley-III cognitive and motor scores were lower in infants with severe ROP. Severe ROP is associated with maturational delay in the optic radiations, PLIC, external capsule and posterior white matter, housing the primary visual and motor pathways, and is associated with poorer cognitive and motor outcomes at 18 months' CA. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

To examine whether embryo biopsy for preimplantation genetic diagnosis (PGD) influences neonatal outcomes. Prospective follow-up cohort. Tertiary university-affiliated medical center. 242 children born after PGD, 242 children born after intracytoplasmic sperm injection (ICSI) (158 singletons and 42 twins pairs in each group), and 733 children born after a spontaneous conception (SC) (493 singletons, 120 twins pairs), matched for maternal age, parity, and body mass index. None. Gestational age, birth weight, prematurity (<37 and <34 weeks), low birth weight (<2,500 g, very low birth weight, <1,500 g), and intrauterine growth restriction (<10th percentile for gestational age). For singletons, the mean birth weight was higher after SC compared with ICSI but not compared with PGD. Mean gestational ages were lower after PGD and ICSI compared with SC. The low birth weight and intrauterine growth restriction rates were 4.4%, 12.0%, and 5.7% and 5.1%, 9.5%, and 5.5% for PGD, ICSI, and SC, respectively. Similar results were found when controlled for the number of embryos transferred and cryopreservation. The results for twins exhibited similar but less statistically significant trends. Polar body and blastomere biopsies provided similar outcomes. Embryo biopsy itself did not cause intrauterine growth restriction or low birth weight compared with SC, despite lower gestational ages with PGD. The worsened outcomes in ICSI compared with PGD pregnancies may be due to the infertility itself. Copyright © 2014 American Society for Reproductive Medicine. Published by Elsevier Inc.

A major cause of perinatal morbidity and mortality has been reported to be preterm premature rupture of membranes (PPROM). Our objective was to evaluate oxidant-antioxidant balance, infection parameters, time interval between rupture of membranes and delivery (latency period), and the relationship among all these parameters. Seventy-five cases with PPROM between 24 and 34 gestational weeks were included in the study. A control group of 41 women who gave birth at term were considered as the control group. The relationship among maternal plasma total oxidative stress (TOS), malondialdehyde (MDA), total antioxidant status (TAS), leukocyte counts, CRP, vitamin C and E levels, gestational week, neonatal birthweight, and latency period was evaluated. In cases with PPROM, rupture occurred at an average of 29.4 gestational weeks and premature babies were born at an average of 31.6 gestational weeks. The mortality rate of babies born to PPROM women was 18.7% (14/75) died at or following birth. In the PPROM group, TOS, MDA, and leukocyte counts were found to be significantly higher compared to the control group (p < 0.001). Besides, a significant negative correlation was detected among the latency period, TOS, CRP, and leukocyte counts (p < 0.05). Appropriate treatment protocols that strengthen antioxidant defense systems and taking into consideration the signs of infection can decrease the incidence of PPROM and/or mortality rates of babies born to PPROM women.

Intra-amniotic inflammation with preterm premature rupture of membranes (PPROM) is a risk factor for fetal inflammatory response syndrome (FIRS) and adverse neonatal outcome. To evaluate the diagnostic accuracy of lipopolysaccharide-binding protein (LBP) for detecting FIRS in preterm neonates born after PPROM. This was a prospective study in the level III neonatal intensive care unit (42 neonates; 23 + 6 to 31 + 6 weeks' gestation) of mothers with PPROM. Umbilical cord blood concentrations of LBP, C-reactive protein (CRP), interleukin (IL)-6 and white blood cell count with differential were measured at delivery and 24 h after birth. Neonates were classified into FIRS (n = 22) and no FIRS (n = 20) groups according to clinical criteria and IL-6 level (≥17.5 pg/ml). Histological examination of the placenta and umbilical cord was performed. Neurological examination at 12 months' corrected age was performed. Umbilical cord blood concentration of LBP was significantly higher in the FIRS group than in the no FIRS group at delivery (median 21.6 mg/l vs. median 2.3 mg/l; p < 0.0001) and 24 h after birth (median 17.2 mg/l vs. median 20.0 mg/l; p < 0.001). The area under the ROC curve for FIRS at delivery was 0.98 (95% CI 0.88-1.0) for LBP, 0.92 (95% CI 0.80-0.99) for CRP and 0.82 (95% CI 0.64-0.94) for immature to total neutrophil ratio. Similar results were obtained if FIRS was defined by funisitis. Umbilical cord blood concentration of LBP at delivery was significantly higher in neonates with abnormal neurological exam at 12 months than in those with normal exam (median 19.5 mg/l vs. median 3.75 mg/l; p < 0.015). In preterm neonates born to asymptomatic women with PPROM, LBP in cord blood at delivery is an excellent diagnostic biomarker of FIRS/funisitis with prognostic potential. © 2013 S. Karger AG, Basel.

Full Text Available Research question: Which are the maternal, socio-demographic and neonatal attributes responsible for neonatal mortality in rural areas of Gujarat? Objectives: (i To know various maternal, socio-demographic and neonatal factors responsible for neonatal mortality in rural areas of Gujarat (ii To estimate neonatal mortality rate in the area. Setting: Rural areas of six Primary Health Centers of Jamnagar district of Gujarat State. Study design: Community based cohort study. Sample size: Population of 40512 Participants: Members of the family in which neonatal deaths occurred. Outcome variable: Neonatal mortality Analysis: Sample proportions. Results: Neonatal mortality rate on the basis of follow-up of births during one year was found to be 47.27 per thousand live births. The major maternal and socio-demographic factors responsible for neonatal mortality were; maternal age, illiteracy, lack of antenatal care, closely spaced pregnancies, delivery conducted at home, delivery conducted untrained personnel and delayed initiation of breast feeding. The major neonatal factors responsible for mortality in neonates were; low birth weight, prematurity, first order of birth, early phase of neonatal period, male gender of the child. The leading causes of neonatal mortality were found to be prematurity, birth asphyxia, neonatal infections and congenital anomalies.

BACKGROUND: The importance of paternal determinants in the occurrence of low birthweight and prematurity is not well known. We investigated these outcomes in siblings and paternal half siblings as a function of changes in putative external determinants between two births in fathers who had...... experienced the birth of a premature and/or low birthweight (PTB/LBW) infant. METHODS: All fathers who, between 1980 and 1992, had an infant born before 37 completed weeks' gestation or weighing

In this article, seven families describe their experiences giving birth to and raising a premature baby. Their perspectives vary, one from another, and shift over time, depending on each family's circumstances and the baby's developmental course. Experiences discussed include premature labor, medical interventions and the NICU, bringing the baby…
Premature ovarian failure is characterized by secondary amenorrhea affecting a woman before the age of 40, leading to hypoestrogenism, infertility, and consequences of premature menopause, such as osteoporosis, cardiovascular disease, neurovegetative alterations, and others. Follicular exhaustion is due to either follicles shortage or oocytes accelerated destruction. Main causes are genetic, autoimmune and iatrogenic. Among genetic causes Xq and Xp deletions, translocations, numeric aberratio...

Prematurity and small-for-gestational age (SGA) neonates are at risk for postnatal complications. Concentrations of total homocysteine (tHcy) might be related to neonatal outcome. We hypothesized that concentrations of tHcy are not related to growth restriction in neonates from mothers receiving 5 mg/day folic acid. We studied a total of 133 preterm neonates from normotensive mothers; SGA (n=96) and appropriate-for-gestational age (AGA, n=37). Concentrations of tHcy, folate and vitamin B12 were measured in venous umbilical cord plasma. AGA preterm neonates had higher mean birth weight (BW) compared to SGA preterms (2472 g vs. 2007 g; pgestational age (GA) (35.1 vs. 35.7 weeks; p=0.059). Concentrations of tHcy (4.86 vs. 4.95 micromol/L), folate (63.3 vs. 55.7 nmol/L), and vitamin B12 (409 vs. 394 pmol/L) were not significantly different between the groups. GA was a strong positive predictor, BW was a significant negative predictor of cord plasma folate. Vitamin B12 concentration was a significant negative predictor of cord tHcy. Concentrations of tHcy did not differ between SGA and AGA preterm neonates born to mothers supplemented with folic acid. This finding argues against a causal role for folate deficiency or increased tHcy in growth restriction.
Full Text Available The aim of this paper is to present a systematic literature review of the researches conducted in the area of risk factors and difficulties in the early development of children born after assisted conception, to systematize current knowledge in this field and allocate the factors of importance for the early intervention.In order to evaluate the published data on risk factors and early development of children born after assisted conception, an extensive literature search was conducted to identify the published papers related to the obstetric and neonatal outcome of pregnancies after assisted reproduction technology, the incidence of multiple pregnancy and the risk of preterm delivery, the neonatal status, the mean gestational age, the average birth weight, the neuro-developmental outcomes and early cognitive and motor development. The research identified the following factors as the most important for the early intervention: increased rates of multiple gestations, prematurity, delivery by cesarean section, lower average gestational development and average birth weight, small fetal development for gestational age and low Apgar score, related to the an increased risk of developing neurological problems, such as the cerebral palsy.Accepting this research results, it can be concluded that all of these information should be available for couples seeking an Assisted Reproductive Technology (ART treatment.The success of the early intervention is directly related to the early detection and assessment that precedes this treatment, creating individual programs and evaluation of the effects of the treatment.

We evaluated 2-year neurodevelopmental outcomes in children with gastroschisis. We reviewed the records of children with gastroschisis treated between August 2001 and July 2008. Children discharged from the neonatal intensive care unit were referred to the state-sponsored Developmental Tracking Infant Progress Statewide (TIPS) program. We reviewed TIPS assessments performed before age 2 years. School districts evaluated children referred by TIPS and determined their eligibility for early intervention services. Poor outcomes were defined as scores of "failure" or "moderate/high risk" on the screening assessment or enrollment in early intervention services by 2 years. Children with gastroschisis were compared with case-matched nonsurgical, nonsyndromic children of similar gestational age and birth weight. One hundred five children were born with gastroschisis, and 46 were followed up with TIPS. There was no statistically significant difference in performance on screening assessments or in the rate of enrollment in early intervention services between the gastroschisis children and controls. Children born with gastroschisis have similar 2-year neurodevelopmental outcomes as nonsurgical, nonsyndromic neonatal intensive care unit children of similar gestational age and birth weight. Both groups of children have a higher rate of enrollment in early intervention than their healthy peers. These data suggest that neurodevelopmental outcomes in gastroschisis children are delayed secondary to prematurity rather than the presence of the surgical disease. Copyright © 2012 Elsevier Inc.

Up to two-thirds of premature born neonates are treated for infections with aminoglycosides such as gentamicin. Although acute toxicities are well described, there is uncertainty on developmental changes after treatment of premature born neonates. We studied the effect of gentamicin and ceftazidime on kidney development in the rat. Additionally, we evaluated the modulating effect of extrauterine growth restriction. On postnatal day (PND) 2, Wistar rats were cross-fostered into normal sized litters (12 pups) or large litters (20 pups) to create normal food (NF) or food restricted (FR) litters to simulate growth restriction and dosed daily intraperitoneally with placebo, 4 mg/kg of gentamicin or 50 mg/kg ceftazidime until PND 8. Gentamicin pharmacokinetics were studied in a separate group of animals. Kidneys were weighed. Renal expression of 18 developmental genes was evaluated by quantitative PCR on PND 8. On PND 35, glomerular number was assessed by stereology and glomerular generations were counted. Food restricted litters showed 22% less body weight compared with controls by day 35 (p kidney development, ceftazidime can affect Renin expression, and extrauterine growth restriction impairs kidney development, but did not modulate potential drug toxicity.

In March 2010, a new legislation about assisted reproductive technology (ART) activities, favoring single embryo transfer, was introduced in Turkey. Consequences of new regulations on neonatal outcome have not been evaluated in multicenter studies yet. In this study, our aim was to evaluate neonatal outcome of infants from medically assisted reproduction (MAR) pregnancies in the post-legislation era. A point prevalence study was conducted at 51 centers in Turkey on 1 April 2013. Data about fertility treatments and neonatal characteristics were evaluated for "live births" (Group 1) and "patients being cared in the NICU" (Group 2). Seventeen (4%) of 420 infants in group 1, and 89 (8.1%) of 1094 infants in group 2 were born after MAR pregnancies. The ratio of multiple births in MAR pregnancies was still very high as 47.1% for group 1, 69.1% for group 2 infants. MAR babies constituted 9.9% of infants in Level 3 NICUs and 7.6% infants in Level 2 NICUs. MAR was associated with increased risk of multiple births and prematurity. After the new legislation, multiple birth rates are still high in MAR pregnancies, resulting in unfavorable neonatal outcomes. Efforts to decrease multiple birth rates should be encouraged.

To investigate the effect of transcervical amnioinfusion on the management of labour and neonatal outcomes in preterm premature rupture of the membranes. This clinical trial included 86 patients with premature rupture of the membranes between weeks 27 and 35 of gestation. Patients were randomly assigned to receive amnioinfusion via a two-way catheter or to the control group. Clinical management was otherwise the same in both groups. Amnioinfusion decreased the frequency of variable decelerations in fetal heart rate (27.9% versus 53.5%, pamnioinfusion for preterm premature rupture of the membranes reduced the number of interventions needed because of nonreassuring fetal status, and improved neonatal gasometric values without increasing maternal or fetal morbidity.

Full Text Available The aim was to describe current reports in the scientific literature on sleep in the intensive care environment and sleep deprivation associated with painful experiences in premature infant. A systematic search was conducted for studies on sleep, pain, premature birth and care of the newborn. Web of Knowledge, MEDLINE, LILACS, Cochrane Library, PubMed, EMBASE, Scopus, VHL and SciELO databases were consulted. The association between sleep deprivation and pain generates effects that are observed in the brain and the behavioral and physiological activity of preterm infants. Polysomnography in intensive care units and pain management in neonates allow comparison with the first year of life and term infants. We have found few references and evidence that neonatal care programs can influence sleep development and reduce the negative impact of the environment. This evidence is discussed from the perspective of how hospital intervention can improve the development of premature infants.

Newborns with intrauterine hypotrophy are at particular risk group of neonates. Diagnosis based on an adequate estimated gestational age, compared with accurate anthropometric measurements after birth. Among children born with low birth weight (leading experts in obstetrics, perinatal and neonatal medicine, pediatricians endocrinologists, pharmacologists and epidemiologists, with the following main tasks: the definition of small for gestational age children, diagnosis of SGA, SGA children growth and role of growth hormone in their treatment. Subsequent meetings of this committee discuss consensus on SGA infants who acquire their final form at a meeting in Prague in 2009 Small for gestational age (SGA, SGA), is described children whose body weight and/or height is lower than the average by more than 2 standard deviations (< - 2SD). Some authors use the boundary 3rd, 5th, or 10th percentile, but most believe that the use of indicators (< - 2SD) comprises the largest percentage of newborns with fetal growth disorders. Small for gestational age children are divided into: newborn weight retardation (SGAW), growth retardation (SGAL), matched up in weight and height (SGAWL). "Intrauterine growth retardation" (Intra-Uterine Growth Retardation (IUGR) are born with fetal growth retardation, documented at least two ultrasound scans, one of which in the 1st trimester Intrauterine hypotrophy is the second most common cause of perinatal death after prematurity. Hypotrophy is present in about 53% of premature and stillborn at 26% of full-term stillborn children. The incidence of asphyxia in SGA intrapartum is about 50%. Neonatal care includes effective primary resuscitation, treatment of existing and prevention of complications anticipated adaptation. These children are subject to follow-up for later risk of socially significant diseases in the adult.

Childhood asthma and premature birth are both common; however, no studies have reported urbanization association between asthma and prematurity and the duration of prematurity affect asthma development. We use Taiwan Longitudinal Health Insurance Database (LHID) to explore association between asthma and prematurity among children by using a population-based analysis. This is a retrospective cohort study with registration data derived from Taiwan LHID. We evaluated prematurely born infants and children aged prematurely and 13 851 (40.27 per 1000 person-years) controls. The hazard ratio for asthma during 5-year follow-up period was 1.95 (95% confidence interval = 1.67-2.28) among children born prematurely. Boys born prematurely aged 0-2 years were associated with higher asthma rates compared with girls in non-premature and premature groups. Living in urban areas, those born prematurely were associated with higher rates of asthma compared with non-prematurity. Those born prematurely lived in northern region had higher asthma hazard ratio than other regions. Our analyses indicated that sex, age, urbanization level, and geographic region are significantly associated with prematurity and asthma. Based on cumulative asthma-free survival curve generated using the Kaplan-Meier method, infants born prematurely should be closely monitored to see if they would develop asthma until the age of 6 years.
Full Text Available Background: The appropriate moment for clamping the umbilical cord is controversial. Immediate cord clamping (ICC is an item of active management of the third stage of labor (AMTSL. Unclamped umbilical cord may cause inconvenience in preterm neonates because they commonly need some levels of emergent services. Some studies revealed delayed cord clamping (DCC of preterm neonates results in better health conditions like lower rates of respiratory distress syndrome (RDS, less morbidities in labor room and lower risk of postpartum hemorrhage. The aim of the present study was to determine the effect of delayed umbilical cord clamping on premature neonatal outcomes. Materials and Methods: In this single‑center randomized control trial study, sixty premature neonates (gestational age ≤ 34 weeks were randomly assigned to ICC (cord clamped at 5–10 seconds or DCC (30–45 seconds groups and followed up in neonatal intensive care unit (NICU. Primary outcomes were 1st and 5th minute Apgar score, average of level of hematocrit after birth, intra ventricle hemorrhage and need some levels of resuscitation. Results: Differences in demographic characteristics were not statistically significant. After birth, neonates who had delayed clamping had significantly higher mean hematocrit after at 4-hour of birth (49.58+5.15gr/dl vs. 46.58+5.40gr/dlin DCC vs. ICC groups, respectively (P=0.031. Delayed cord clamping reduced the duration of need to nasal continues positive airway pressure (NCPAP (86.7% and 60.0% in ICC and DCC groups, respectively, P= 0.039. Attractively, the results showed lower incidence of clinical sepsis in delayed cord clamping neonates (53.3% vs. 23.3% in ICC and DCC groups, respectively, P=0.033. Conclusion: Prematurity complications might decrease by delay umbilical cord clamping which improve the hematocrit, duration of need to NCPAP and incidence of clinical sepsis. Furthermore, DCC may have no negative impact on neonatal resuscitation.
Full Text Available Conventional magnetic resonance imaging (MRI at term equivalent age (TEA is suggested to be a reliable tool to predict the outcome of very premature infants. The objective of this study was to determine simple reproducible MRI indices, in premature infants and to analyze their neonatal determinants at TEA. A cohort of infants born before 32 weeks gestational age (GA underwent a MRI at TEA in our center. Two axial images (T2 weighted, were chosen to realize nine measures. We defined 4 linear indices (MAfhlv: thickness of lateral ventricle; CSI: cortex-skull index; VCI: ventricular-cortex index; BOI: bi occipital index and 1 surface index (VS.A: volume slice area. Perinatal data were recorded. Sixty-nine infants had a GA (median (interquartile range of 30.0 weeks GA (27.0; 30.0 and a birth weight of 1240 grams (986; 1477. MRI was done at 41.0 (40.0; 42.0 weeks post menstrual age (PMA. The inter-investigator reproducibility was good. Twenty one MRI (30.5% were quoted abnormal.

There was a difference for VCI between normal and abnormal MRI (0.412 (0.388; 0.429 vs. 0.432 (0.418; 0.449; p = 0,019; BOI was higher when fossa posterior lesions were observed; VS.A seems to be the best surrogate for cerebral volume, 80% of VS.As' variance being explained by a multiple linear regression model including 7 variables (head circumference at birth and at TEA, PMA, dopamine, ibuprofen treatment, blood and platelets transfusions. These indices, easily and rapidly achievable, seem to be useful but need to be validated in a large population to allow generalization for diagnosis and follow-up of former premature infants.

Full Text Available Initial audiological test was performed in 136 premature children with various gestational age born from single fetation. The children were divided into 2 groups: prematures with intrauterine growth restriction (IUGR and prematures with normal weight for their gestational age (normotrophy. The study showed that the rate of passing the initial audiological test using the method of DPOAE was lower in both ears in children with IUGR, than in children with normotrophy. The correlation between the results of initial audiological test and birth weight was found: the lower was weight, the higher was risk of absence of acoustic response registration on initial examination.

To investigate whether neonatal hyperglycaemia in the first postnatal week is associated with treatment-demanding retinopathy of prematurity (ROP). This is a Danish national, retrospective, case-control study of premature infants (birth period 2003-2006). Three national registers were searched, and data were linked through a unique civil registration number. The study sample consisted of 106 cases each matched with two comparison infants. Matching criteria were gestational age (GA) at birth, ROP not registered and born at the same neonatal intensive care unit. Potential 'new' risk factors were analysed in a multivariate logistic regression model, while adjusted for previously recognised risk factors (ie, GA at birth, small for gestational age, multiple birth and male sex). Hospital records of 310 preterm infants (106 treated; 204 comparison infants) were available. Nutrition in terms of energy (kcal/kg/week) and protein (g/kg/week) given to the preterm infants during the first postnatal week were statistically insignificant between the study groups (Mann-Whitney U test; p=0.165/p=0.163). Early postnatal weight gain between the two study groups was borderline significant (t-test; p=0.047). Hyperglycaemic events (indexed value) were statistically significantly different between the two study groups (Mann-Whitney U test; p<0.001). Hyperglycaemia was a statistically independent risk factor (OR: 1.022; 95% CI 1.002 to 1.042; p=0.031). An independent association was found between the occurrence of hyperglycaemic events during the first postnatal week and later development of treatment-demanding ROP, when adjusted for known risk factors. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Background Almost one million prematurely born infants die annually from respiratory insufficiency, predominantly in countries with limited access to respiratory support for neonates. The primary hypothesis tested in the present study was that a modified device for bubble nasal continuous positive airway pressure (Bn-CPAP) would provide lower work of spontaneous breathing, estimated by esophageal pressure-rate products. Methods Infants born CPAP with FiO2 CPAP, then 2 h with Bn-CPAP using a modified bubble device presently termed Seattle-PAP, which produces a different pattern of pressure fluctuations and which provided greater respiratory support in preclinical studies, then 2 h on standard Bn-CPAP. Results All 40 infants enrolled completed the study and follow-up through 36 wks post menstrual age or hospital discharge, whichever came first. No infants were on supplemental oxygen at completion of follow-up. No infants developed pneumothoraces or nasal trauma, and no adverse events attributed to the study were observed. Pressure-rate products on the two devices were not different, but effort of breathing, assessed by areas under esophageal pressure-time curves, was lower with Seattle-PAP than with standard Bn-CPAP. Conclusion Use of Seattle-PAP to implement Bn-CPAP lowers the effort of breathing exerted even by relatively healthy spontaneously breathing premature neonates. Whether the lower effort of breathing observed with Seattle-PAP translates to improvements in neonatal mortality or morbidity will need to be determined by studies in appropriate patient populations.

Full Text Available Recent neuroimaging findings have highlighted the impact of premature birth on subcortical development and morphological changes in the deep grey nuclei and ventricular system. To help characterize subcortical microstructural changes in preterm neonates, we recently implemented a multivariate tensor-based method (mTBM. This method allows to precisely measure local surface deformation of brain structures in infants. Here, we investigated ventricular abnormalities and their spatial relationships with surrounding subcortical structures in preterm neonates. We performed regional group comparisons on the surface morphometry and relative position of the lateral ventricles between 19 full-term and 17 preterm born neonates at term-equivalent age. Furthermore, a relative pose analysis was used to detect individual differences in translation, rotation, and scale of a given brain structure with respect to an average. Our mTBM results revealed broad areas of alterations on the frontal horn and body of the left ventricle, and narrower areas of differences on the temporal horn of the right ventricle. A significant shift in the rotation of the left ventricle was also found in preterm neonates. Furthermore, we located significant correlations between morphology and pose parameters of the lateral ventricles and that of the putamen and thalamus. These results show that regional abnormalities on the surface and pose of the ventricles are also associated with alterations on the putamen and thalamus. The complementarity of the information provided by the surface and pose analysis may help to identify abnormal white and grey matter growth, hinting toward a pattern of neural and cellular dysmaturation.

Full Text Available to improve treatment results in premature infants with neonatal respiratory distress syndrome (NRDS, by establishing developmental mechanisms and elaborating methods for its early diagnosis, treatment, and prevention. Material and methods. The paper analyzes the results of a clinical observation and laboratory, instrumental, immunological, morphological, and radiological studies of 320 premature neonates at 26—35 weeks gestational age. The following groups of neonates were identified: 1 40 premature neonatal infants without NRDS and with the physiological course of an early neonatal period (a comparison group; 2 190 premature neonates with severe NRDS in whom the efficiency of therapy with exogenous surfactants, such as surfactant BL versus curosurf, was evaluated; 3 90 premature newborn infants who had died from NRDS at its different stages. Results. The poor maternal somatic, obstetric, and gynecological histories in the early periods of the current pregnancy create prerequisites for its termination, favor the development of severe acute gestosis, and cause abnormal placental changes. Each gestational age is marked by certain placental changes that promote impaired uterineplacentalfetal blood flow and premature birth. Alveolar and bronchial epithelial damages, including those ante and intranatally, microcircula tory disorders play a leading role in the tanatogenesis of NRDS. Intranatal hypoxia and amniotic fluid aspiration are one of the important factors contributing to alveolar epithelial damage and NRDS in premature neonates. Exogenous surfactants prevent the development of hyaline membranes and are useful in the normalization of ventilation-perfusion relationships and lung biomechanical properties. Conclusion. This study could improve the diagnosis and treatment of NRDS, which assisted in reducing the duration of mechanical ventilation from 130±7.6 to 65±11.6 hours, the number of complications (the incidence of intragastric

Retinopathy of prematurity is a proliferative retinal disorder diagnosed exclusively in prematurely born infants. In retinopathy of prematurity, growth of the retinal vasculature is disturbed, leading to hypoxia-induced pathological changes typical of retinopathy of prematurity, in the worst case resulting in retinal detachment. The most typical risk factors predisposing to the disease include hyperoxemia, low levels of insulin-like growth factor 1 (IGF-I), and low birth weight in relation to weeks of pregnancy. Laser therapy of peripheral retina is the currently established form of treatment. Screening is applied in order to recognize the pathological changes in retinopathy of prematurity early enough.

Human neonates prefer listening to speech compared to many nonspeech sounds, suggesting that humans are born with a bias for speech. However, neonates' preference may derive from properties of speech that are not unique but instead are shared with the vocalizations of other species. To test this, thirty neonates and sixteen 3-month-olds were…
Full Text Available Background: Advances in perinatal and neonatal care have increased the survival of extremely preterm infants, but the viability limit is still debated. Here we assess the survival, neonatal morbidity, and neurodevelopmental outcomes at 2 years of age of infants born at 22–26 weeks of gestation in Taiwan between 2007 and 2011. Methods: This is a prospective longitudinal multicenter cohort study on extremely preterm infants registered in the Taiwan Premature Infant Developmental Collaborative Study Group from 2007 to 2011, including 22 neonatal care centers. We extracted demographic and clinical data of infants born at 22–26 weeks, and obtained growth and developmental outcome data from the follow-up clinic at 24 months of corrected age. Multivariate analyses using a logistic regression model identified factors significantly impacting survival. Results: 647 of the 1098 infants included in the study (58.9% survived to discharge. Survival rates were 8% (4/50, 25% (27/108, 46.8% (117/250, 67.0% (211/315, and 76.8% (288/375 for infants born at 22, 23, 24, 25, and 26 weeks, respectively. Most survivors (567/647, 87.6% had major morbidities during hospitalization, and we identified factors that positively and negatively affected survival. 514 (79.4% patients received follow-up evaluation at 2 years, and 204 (39.7% of them had neurodevelopmental impairment (NDI with an incidence of 75%, 65.2%, 49.5%, 39.5%, and 32.8% for infants born at 22, 23, 24, 25, and 26 weeks, respectively. Conclusion: Infants born at 22 and 23 weeks have a very low likelihood of surviving with little or no impairment. These findings are valuable for parental counseling and perinatal care decisions.

Learning difficulties are frequently diagnosed in children born with intrauterine growth restriction (IUGR). Models of various animal species with IUGR were studied and demonstrated specific susceptibility and alterations of the hippocampal formation and its related neural structures. The main purpose was to study memory functions of children born with asymmetric IUGR in a large-scale cohort using a long-term prospective paradigm. One hundred and ten infants diagnosed with IUGR were followed-up from birth to 9 years of age. Their performance was compared with a group of 63 children with comparable gestational age and multiple socioeconomic factors. Memory functions (short-term, super- and long-term spans) for different stimuli types (verbal and visual) were evaluated using Visual Auditory Digit Span tasks (VADS), Rey Auditory Verbal Learning Test (Rey-AVLT), and Rey Osterrieth Complex Figure Test (ROCF). Children with IUGR had short-term memory difficulties that hindered both serial verbal processing system and simultaneous processing of high-load visuo-spatial stimuli. The difficulties were not related to prematurity, neonatal complications or growth catch-up, but were augmented by lower maternal education. Recognition skills and benefits from reiteration, typically affected by hippocampal dysfunction, were preserved in both groups. Memory profile of children born with IUGR is characterized primarily by a short-term memory deficit that does not necessarily comply with a typical hippocampal deficit, but rather may reflect an executive short-term memory deficit characteristic of anterior hippocampal-prefrontal network. Implications for cognitive intervention are discussed.
Following years of research there have been some significant developments in the understanding and subsequent support being offered to Neonatal Intensive Care Unit (NICU) families. In addition, ground breaking advances in the treatment of premature infants, with specific interest in the role of human milk, are now available. New information was presented by leading international researcher, Professor Meier, at an international symposium earlier this year. This article seeks to share this insightful information and provide support to those working in or around the NICU.

Full Text Available Abstract Background Reduction in neonatal mortality has been slower than anticipated in many low income countries including Tanzania. Adequate neonatal care may contribute to reduced mortality. We studied factors associated with transfer of babies to a neonatal care unit (NCU in data from a birth registry at Kilimanjaro Christian Medical Centre (KCMC in Tanzania. Methods A total of 21 206 singleton live births registered from 2000 to 2008 were included. Multivariable analysis was carried out to study neonatal transfer to NCU by socio-demographic factors, pregnancy complications and measures of the condition of the newborn. Results A total of 3190 (15% newborn singletons were transferred to the NCU. As expected, neonatal transfer was strongly associated with specific conditions of the baby including birth weight above 4000 g (relative risk (RR = 7.2; 95% confidence interval (CI 6.5-8.0 or below 1500 g (RR = 3.0; 95% CI: 2.3-4.0, five minutes Apgar score less than 7 (RR = 4.0; 95% CI: 3.4-4.6, and preterm birth before 34 weeks of gestation (RR = 1.8; 95% CI: 1.5-2.1. However, pregnancy- and delivery-related conditions like premature rupture of membrane (RR = 2.3; 95% CI: 1.9-2.7, preeclampsia (RR = 1.3; 95% CI: 1.1-1.5, other vaginal delivery (RR = 2.2; 95% CI: 1.7-2.9 and caesarean section (RR = 1.9; 95% CI: 1.8-2.1 were also significantly associated with transfer. Birth to a first born child was associated with increased likelihood of transfer (relative risk (RR 1.4; 95% CI: 1.2-1.5, while the likelihood was reduced (RR = 0.5; 95% CI: 0.3-0.9 when the father had no education. Conclusions In addition to strong associations between neonatal transfer and classical neonatal risk factors for morbidity and mortality, some pregnancy-related and demographic factors were predictors of neonatal transfer. Overall, transfer was more likely for babies with signs of poor health status or a complicated pregnancy. Except for a possibly reduced use of transfer

Early life stress can alter hypothalamic pituitary adrenal (HPA) axis function. Differences in cortisol levels have been found in preterm infants exposed to substantial procedural stress during neonatal intensive care, compared to infants born full-term, but only a few studies investigated whether altered programming of the HPA axis persists past toddler age. Further, there is a dearth of knowledge of what may contribute to these changes in cortisol. This prospective cohort study examined the cortisol profiles in response to the stress of cognitive assessment, as well as the diurnal rhythm of cortisol, in children (n=129) born at varying levels of prematurity (24-32 weeks gestation) and at full-term (38-41 weeks gestation), at age 7 years. Further, we investigated the relationships among cortisol levels and neonatal procedural pain-related stress (controlling for multiple medical confounders), concurrent maternal factors (parenting stress, depressive and anxiety symptoms) and children's behavioral problems. For each aim we investigate acute cortisol response profiles to a cognitive challenge as well as diurnal cortisol patterns at home. We hypothesized that children born very preterm will differ in their pattern of cortisol secretion from children born full-term, possibly depended on concurrent child and maternal factors, and that exposure to neonatal pain-related stress would be associated with altered cortisol secretion in children born very preterm, possibly in a sex-dependent way. Saliva samples were collected from 7-year old children three times during a laboratory visit for assessment of cognitive and executive functions (pretest, mid-test, end-study day acute stress profile) and at four times over two consecutive non-school days at home (i.e. morning, mid-morning, afternoon and bedtime-diurnal rhythm profile). We found that cortisol profiles were similar in preterm and full-term children, albeit preterms had slightly higher cortisol at bedtime compared to
Full Text Available Abstract Background Gaps between research knowledge and practice have been consistently reported. Traditional ways of communicating information have limited impact on practice changes. Strategies to disseminate information need to be more interactive and based on techniques reported in systematic reviews of implementation of changes. There is a need for clarification as to which dissemination strategies work best to translate evidence into practice in neonatal units across England. The objective of this trial is to assess whether an innovative active strategy for the dissemination of neonatal research findings, recommendations, and national neonatal guidelines is more likely to lead to changes in policy and practice than the traditional (more passive forms of dissemination in England. Methods/design Cluster randomised controlled trial of all neonatal units in England (randomised by hospital, n = 182 and stratified by neonatal regional networks and neonatal units level of care to assess the relative effectiveness of active dissemination strategies on changes in local policies and practices. Participants will be mainly consultant lead clinicians in each unit. The intervention will be multifaceted using: audit and feedback; educational meetings for local staff (evidence-based lectures on selected topics, interactive workshop to examine current practice and draw up plans for change; and quality improvement and organisational changes methods. Policies and practice outcomes for the babies involved will be collected before and after the intervention. Outcomes will assess all premature babies born in England during a three month period for timing of surfactant administration at birth, temperature control at birth, and resuscitation team (qualification and numbers present at birth.

Full Text Available Objectives: This study aimed to evaluate the changing survival rate and morbidities among infants born before 26 gestational weeks at the Sultan Qaboos University Hospital (SQUH in Muscat, Oman. Methods: This retrospective study assessed the mortality and morbidities of all premature infants born alive at 23–26 gestational weeks at SQUH between June 2006 and May 2013. Infants referred to SQUH within 72 hours of birth during this period were also included. Electronic records were reviewed for gestational age, gender, birth weight, maternal age, mode and place of delivery, antenatal steroid administration, morbidity and outcome. The survival rate was calculated and findings were then compared with those of a previous study conducted in the same hospital from 1991 to 1998. Rates of major morbidities were also calculated. Results: A total of 81 infants between 23–26 gestational weeks were admitted to the neonatal unit during the study period. Of these, 58.0% were male and 42.0% were female. Median gestational age was 25 weeks and mean birth weight was 770 ± 150 g. Of the 81 infants, 49 survived. The overall survival rate was 60.5% compared to 41% reported in the previous study. Respiratory distress syndrome (100.0%, retinopathy of prematurity (51.9%, bronchopulmonary dysplasia (34.6%, intraventricular haemorrhage (30.9% and patent ductus arteriosus (28.4% were the most common morbidities. Conclusion: The overall survival rate of infants between 23–26 gestational weeks during the study period had significantly improved in comparison to that found at the same hospital from 1991 to 1998. There is a need for the long-term neurodevelopmental follow-up of premature infants.

School achievement during the first four grades was analysed by means of subject marks in 203 prematurely born and in 140 maturely born children. In subjects referring to behaviour in the classroom, no statistically significant differences in average marks could be found between prematurely born children and the control group. The average marks in performance subjects were slightly higher in the subgroup of very prematurely born children. However, statistically significant lower marks were observed in the subject of sports only, and for formerly immature children also in the subject of manual training. The higher the educational level of the mothers, the better the average marks without sports. No relationships between school performance and manifestation of postnatal risk factor like Apgar score, blood gas values and duration of oxygen dependency could be seen. These results demonstrate that school performance of former premature infants lies within the normal variance of their grade.

Full Text Available Preeclampsia is a multiorgan, heterogeneous disorder of pregnancy associated with significant maternal and neonatal morbidity and mortality. Optimal strategies in the care of the women with preeclampsia have not been fully elucidated, leaving physicians with incomplete data to guide their clinical decision making. Because preeclampsia is a progressive disorder, in some circumstances, delivery is needed to halt the progression to the benefit of the mother and fetus. However, the need for premature delivery has adverse effects on important neonatal outcomes not limited to the most premature infants. Late-preterm infants account for approximately two thirds of all preterm deliveries and are at significant risk for morbidity and mortality. Reviewed is the current literature in the diagnosis and obstetrical management of preeclampsia, the outcomes of late-preterm infants, and potential strategies to optimize fetal outcomes in pregnancies complicated by preeclampsia.

Comparative study of delivery mode and perinatal outcomes in women with premature rupture of membranes at term compared to those with intact membranes. A cross sectional survey of all deliveries in 39 hospitals in 3 geographic regions of mainland China from January 1 to December 31, 2011 was carried out to investigate the demographic data and delivery outcomes. In our analysis of 103 124 pregnancies, 14 073(13.6%) were complicated by premature rupture of membranes. Compared to those with intact membrane, the risks of postpartum hemorrhage, maternal complications and neonatal complications were increased significantly for women with premature rupture of membranes at term, especially the prevalence of neonatal respiratory distress syndrome(NRDS) and meconium aspiration syndrome. The risk of low Apgar (premature rupture of membranes at term. The adverse perinatal outcomes are slightly higher in women with term premature rupture of membranes than those with intact membrane.

Conclusion: Resistin levels were higher in premature newborns with sepsis and correlated with IL-6 levels, which is an indicator of neonatal sepsis. This suggests that resistin may also be used in the diagnosis of neonatal sepsis. However, it has limited value when compared with the other inflammatory markers including C-reactive protein, procalcitonin, and IL-6.

Intrauterine growth restriction (IUGR) and prematurity have been associated with increased perinatal morbidity and mortality and also with cardiovascular foetal programming. However, there are few studies on the impact of placenta-related IUGR on perinatal outcomes and cardiovascular biomarkers in pre-term infants. To determine differences in neonatal morbidity, mortality and cord blood biomarkers of cardiovascular dysfunction between pre-term placenta-related IUGR and non-IUGR new-borns, and to analyse their relationship with the severity of IUGR according to foetal Doppler evaluation. Prospective cohort study: pre-term infants with placenta-related IUGR and matched pre-term infants without IUGR. A Doppler scan was performed, and placenta-IUGR was classified according to severity. Comparative analysis of perinatal outcomes, neonatal morbidity and mortality, and cord blood levels of biomarkers of cardiovascular dysfunction was performed. IUGR new-borns present lower weight, length, head circumference, and Apgar score at birth, as well as increased neonatal and cardiovascular dysfunction biomarker levels, compared with pre-term new-borns without IUGR. These differences increase with the severity of IUGR determined by prenatal umbilical artery Doppler scan. Placenta-related-IUGR pre-term infants, irrespective of gestational age, present increased neonatal morbidity and mortality that is significantly proportional to the severity of IUGR. Placental impairment and severity also determine levels of cardiovascular dysfunction biomarkers at birth. Copyright © 2015 Asociación Española de Pediatría. Publicado por Elsevier España, S.L.U.

1. We have reviewed 34 cases of neonatal intracranial hemorrhages (perinatal onset, 23 mature and 11 premature infants) experienced in 10-year period from 1971 to 1980, with special reference to gestational age, birth weight, type of delivery, presence or absence of asphyxia, symptoms and cause of death. 2. Regarding 9 autopsied cases and 7 cases diagnosed by CT-scan, 10 mature infants composed of 3 subarachnoid hemorrhages, 2 intraventricular hemorrhages, 2 subdural hematomas, 2 intracerebral and 1 subependymal hemorrhage; 6 premature infants consisted of 4 subependymal hemorrhages with ventricular rupture and 2 subarachnoid hemorrhages. Most of them presented with respiratory distress, vomiting and convulsive seizures which developed within 5 days after birth. 3. Poor outcome including death amounted 49% of mature and 63% of premature infants. Along with degree of intracranial hematoma, prematurity and pulmonary complication were felt to be important prognostic factors. 4. Introduction of CT-scan led to prompt diagnosis and treatment, thus lowering mortality rate of neonatal intracranial hemorrhages. (author)

Infants born prematurely with respiratory distress syndrome are at high risk for complications from mechanical ventilation. Strategies are needed to minimize their days on the ventilator. The purpose of this study was to compare extubation success rates in infants treated with 2 different types of continuous positive airway pressure devices. A retrospective cohort study design was used. Data were retrieved from electronic medical records for patients in a large, metropolitan, level III neonatal intensive care unit. A sample of 194 premature infants with respiratory distress syndrome was selected, 124 of whom were treated with nasal intermittent positive pressure ventilation and 70 with bi-level variable flow nasal continuous positive airway pressure (bi-level nasal continuous positive airway pressure). Infants in both groups had high extubation success rates (79% of nasal intermittent positive pressure ventilation group and 77% of bi-level nasal continuous positive airway pressure group). Although infants in the bi-level nasal continuous positive airway pressure group were extubated sooner, there was no difference in duration of oxygen therapy between the 2 groups. Promoting early extubation and extubation success is a vital strategy to reduce complications of mechanical ventilation that adversely affect premature infants with respiratory distress syndrome.

Full Text Available Objectives: To investigate the incidence, severity and risk factors of retinopathy of prematurity (ROP in triplets. Materials and Methods: The medical records of consecutive premature triplets who had been screened for ROP in a single maternity hospital were analyzed and presence and severity of ROP; birth weight, gender, gestational age of the infant; route of delivery and the mode of conception were recorded. Results: A total of 54 triplets (40 males, 14 females who were screened for ROP between March 2010 and February 2013 were recruited for the study. All triplets were delivered by Caesarean section and 36 (66.7% were born following an assisted conception. During follow-up, seven (13% of the infants developed ROP of any stage and two (3.7% required laser photocoagulation. The mean gestational age of triplets with ROP was 27.6±1.5 (27-31 weeks whereas it was 32.0±1.5 (30-34 weeks in those without ROP (p=0.002. The mean birth weights of triplets with and without ROP were 1290.0±295.2 (970-1600 g and 1667.5±222.2 (1130-1960 g, respectively (p<0.001. The presence of ROP was not associated with gender (p=0.358 or mode of conception (p=0.674. Conclusion: ROP in triplets seems to be mainly related to low gestational age and low birth weight. Further prospective randomized studies are necessary to demonstrate risk factors of ROP in triplets and to determine if and how gemelarity plays a role in the development of ROP.

The ongoing progress in neonatal intensive care is modifying the psychic context of prematurity for all the partners, infants as well as parents and physicians. Comfort and prognosis of preterm infants have much improved. Since newborns under 24 weeks of gestational age are now surviving, they spend approximately half the duration of pregnancy out of the maternal uterus. All the psychological issues of such an early separation have to be considered, including the developmental outcome of a sensorial environment which is quite different from the intra-uterine one. Research has been developing in this field. The cooperation between neonatalogists and psychologists has been profitable to parents. Problems linked to the separation, such as difficulty in representing the infant, are no more frequent owing to the attention paid to the mother-child bond and subsequent early contacts. What is forward now is the impact of an hyper technical world of intensive care on the parents, and of the strange aspect of the tiny baby surrounded by engines and tubes. Such an overpresence of reality often results in a reaction of traumatic daziness among parents. The cooperation of the whole staff is necessary for the resumption of an imaginary process of psychic functioning. Finally, the survival of very-low-birth-weight infants confronts the neonatalogists with some delicate ethical questions. Psychiatrists and psychologists might have an important part to play in aiding the profession in its sorting out of these ethical issues.

Perinatal infection may potentiate brain injury among children born preterm. The objective of this study was to examine whether maternal and/or neonatal infection are associated with adverse outcomes among term neonates with encephalopathy. This study is a cohort study of 258 term newborns with encephalopathy whose clinical records were examined for signs of maternal infection (chorioamnionitis) and infant infection (sepsis). Multivariate regression was used to assess associations between infection, pattern, and severity of injury on neonatal magnetic resonance imaging, as well as neurodevelopment at 30 mo (neuromotor examination, or Bayley Scales of Infant Development, second edition mental development index encephalopathy, chorioamnionitis was associated with a lower risk of brain injury and adverse outcomes, whereas signs of neonatal sepsis carried an elevated risk. The etiology of encephalopathy and timing of infection and its associated inflammatory response may influence whether infection potentiates or mitigates injury in term newborns.
Full Text Available The main objective of the study was to investigate the effect of MID during late pregnancy, assessed by the thyroid-stimulating hormone (TSH concentration at neonatal screening, on cognitive development of preschool children. A retrospective cohort study including 311 Belgian preschool children of 4–6 years old was conducted. Children were selected at random from the total list of neonates screened in 2008, 2009, and 2010 by the Brussels new-born screening center. Infants with congenital hypothyroidism, low birth weight, and/or prematurity were excluded from the selection. The selected children were stratified by gender and TSH-range (0.45–15 mIU/L. Cognitive abilities were assessed using Wechsler Preschool and Primary Scale of Intelligence—third edition. In addition, several socioeconomic, parental, and child confounding factors were assessed. Neonatal TSH concentration—a surrogate marker for MID—was not associated with Full Scale and Performance IQ scores in children. Lower Verbal IQ scores were found in children with neonatal TSH values comprised between 10–15 mIU/L compared to lower TSH levels in univariate analysis but these results did not hold when adjusting for confounding factors. Current levels of iodine deficiency among pregnant Belgian women may not be severe enough to affect the neurodevelopment of preschool children.
Full Text Available Premature ovarian failure (POF, also termed as primary ovarian insufficiency (POI, is a highly heterogenous condition affecting 0.5-3.0% of women in childbearing age. These young women comprise quite a formidable group with unique physical and psychological needs that require special attention. Premature ovarian senescence (POS in all of its forms evolves insidiously as a basically asymptomatic process, leading to complete loss of ovarian function, and POI/POF diagnoses are currently made at relatively late stages. Well-known and well-documented risk factors exist, and the presence or suspicion of autoimmune disorder should be regarded as an important one. Premature ovarian failure is to some degree predictable in its occurrence and should be considered while encountering young women with loss of menstrual regularity, especially when there is a concomitant dysfunction in the immune system.
